commit 371dc4a6d8c3c74a9a1c74b87c2affb3fcef6500 upstream
Comparing apples to bananas doesn't seem right.
The bug has been there since support for the IT8718F was added, so
VID never worked for this chip.

commit eb4400e3a040b90a3ad805b01fcbc99a5f615c8f upstream.
Change spin_locks to irqsave to prevent dead-locks.
Protect adding and deleting to/from dca_providers list.
Drop the lock during dca_sysfs_add_req() and dca_sysfs_remove_req() calls
as they might sleep (use GFP_KERNEL allocation).

This is commit f9c99bb8b3a1ec81af68d484a551307326c2e933 back-ported to
2.6.27.39.
This patch (as1254-2) splits up the shutdown method of usb_serial_driver
into a disconnect and a release method.
The problem is that the usb-serial core was calling shutdown during
disconnect handling, but drivers didn't expect it to be called until
after all the open file references had been closed. The result was an
oops when the close method tried to use memory that had been
deallocated by shutdown.

waiting processes
commit 1f95725755ab67f3198df3b5bf7517f926f310ca upstream.
The s2255 driver had logic which aborted processing of a video frame
if there was no process waiting on the video buffer in question. That
simply doesn't work when the application is doing things in an
asynchronous manner. If the application went to the trouble to queue
the buffer in the first place, then the driver should always attempt
to complete it - even if the application at that moment has its
attention turned elsewhere. Applications which always blocked waiting
for I/O on the capture device would not have been affected by this.
Applications which *mostly* blocked waiting for I/O on the capture
device probably only would have been somewhat affected (frame lossage,
at a rate which goes up as the application blocks less). Applications
which never blocked on the capture device (e.g. polling only) however
would never have been able to receive any video frames, since in that
case this "is anyone waiting on this?" check on the buffer never would
have evalutated true. This patch just deletes that harmful check
against the buffer's wait queue.

commit 96fbf771d86a90ff006bc62ca4d4de6474b3de31 upstream.
Because the counters were not reset when starting up streaming, they would
be reused from the previous run. This can result in cases such that when the
second instance of streaming starts up, the "cnt" variable in
em28xx_audio_isocirq() can end up being negative, resulting in attempting to
write to memory before the start of runtime->dma_area (as well as having a
negative number of bytes to copy).

tda18271_rf_tracking_filters_init
commit a57c1dcb93e43357ed3f666e5a2b5d5071dd3930 upstream.
While having tda18271 module set with debug=17 (cal & info prints) and
cal=0 (delay calibration process until first use) - I discovered that
during the calibration process, if the frequency test for 69750000
returned a bcal of 0 (see tda18721-fe.c in tda18271_powerscan func) that
the tuner wouldn't be able to pickup any of the frequencies in the range
(all the other frequencies bands returned bcal=1). I spent some time
going over the code and the NXP's tda18271 spec (ver.4 of it i think) and
adding a lot of debug prints and walking/stepping through the calibration
process. I found that when the powerscan fails to find a frequency, the
rf calibration is not run and the default value is supposed to be used in
its place (pulled from the RF_CAL_map table) - but something was getting
goofed up there.
Now, my c coding skills are very rusty, but i think root of the problem is
a signedness issue with the math operation for calculating the rf_a1 and
rf_a2 values in tda18271_rf_tracking_filters_init func, which results in
values like 20648 for rf_a1 (when it should probably have a value like 0,
or so slightly negative that it should be zero - this bad value for rf_a1
would in turn makes the approx calc within
tda18271c2_rf_tracking_filters_correction go out of whack). The simplest
solution i found was to explicitly convert the signedness of the
denominator to avoid the implicit conversion. The values placed into the
u32 rf_freq array should never exceed about 900mhz, so i think the s32 max
value shouldn't be an issue in this case.
I've tested it out a little, and even when i get a bcal=0 with the
modified code, the default calibration value gets used, rf_a1 is zero, and
the tuner seems to lock on the stream and mythtv seems to play it fine.

commit 4d8317876d5f53ef792e90f89d8f162d7bca5c81 upstream.
Multiplication by 62500 causes an overflow in the 32 bit freq variable,
which is later divided by 1000 when using FM radio.
This patch prevents the overflow by scaling the frequency value correctly
upfront. Thanks to Henk Vergonet for spotting the problem and providing
a preliminary patch, which this changeset was based upon.

commit 7646b9de26c54cf4bc9c446d7ada9f91ece31e0a upstream.
Fixing kernel oops when driver attemps to load xc2028 firmware.
Note by djh: the patch contribute by Martin is a port of a fix I made during
the PCTV 340e development. It's a temporary workaround that fixes a regression
(an OOPS condition) and the real fix should be in the code that manages the
i2c master on the dib7000p. But this fix does address the immmediate
regression and should be merged upstream until we do a cleaner fix.

commit d9d5283228d0c752f199c901fff6e1405dc91bcb upstream.
In mii monitor mode, bond_check_dev_link() calls the the ioctl
handler of slave devices. It stores the ndo_do_ioctl function
pointer to a static (!) ioctl variable and later uses it to call the
handler with the IOCTL macro.
If another thread executes bond_check_dev_link() at the same time
(even with a different bond, which none of the locks prevent), a
race condition occurs. If the two racing slaves have different
drivers, this may result in one driver's ioctl handler being
called with a pointer to a net_device controlled with a different
driver, resulting in unpredictable breakage.
Unless I am overlooking something, the "static" must be a
copy'n'paste error (?).

commit e9024a059f2c17fb2bfab212ee9d31511d7b8e57 upstream.
On a 64-bit kernel, skb->tail is an offset, not a pointer. The libertas
usb driver passes it to usb_fill_bulk_urb() anyway, causing interesting
crashes. Fix that by using skb->data instead.
This highlights a problem with usb_fill_bulk_urb(). It doesn't notice
when dma_map_single() fails and return the error to its caller as it
should. In fact it _can't_ currently return the error, since it returns
void.
So this problem was showing up only at unmap time, after we'd already
suffered memory corruption by doing DMA to a bogus address.

commit f4b31db92d163df8a639f5a8c8633bdeb6e8432d upstream.
When an internal command fails, it should be failed directly without
invoking EH. In the original implemetation, this was accomplished by
letting internal command bypass failure handling in ata_qc_complete().
However, later changes added post-successful-completion handling to
that code path and the success path is no longer adequate as internal
command failure path. One of the visible problems is that internal
command failure due to timeout or other freeze conditions would
spuriously trigger WARN_ON_ONCE() in the success path.
This patch updates failure path such that internal command failure
handling is contained there.

commit 39acbc12affcaa23ef1d887ba3d197baca8e6e47 upstream.
In this patch:
http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commitdiff;h=16dc42e018c2868211b4928f20a957c0c216126c
the check was added for another driver to already claim the same device
on the same bus. But the returned error code was wrong: to modprobe, the
-EEXIST means that _this_ driver is already installed. It therefore
doesn't produce the needed error message when _another_ driver is trying
to register for the same device. Returning -EBUSY fixes the problem.

commit d50bae33d1358b909ade05ae121d83d3a60ab63f upstream.
"b43: Fix PPC crash in rfkill polling on unload" fixed the bug reported
in Bugzilla No. 14181; however, it introduced a new bug. Whenever the
radio switch was turned off, it was necessary to unload and reload
the driver for it to recognize the switch again.
This patch fixes both the original bug in #14181 and the bug introduced by
the previous patch. It must be stated, however, that if there is a BCM4306/3
with an rfkill switch (not yet proven), then the driver will need an
unload/reload cycle to turn the device back on.

commit 0a3c8549ea7e94d74a41096d42bc6cdf43d183bf upstream.
This patch (as1244) fixes a crash in usb-serial that occurs when a
sub-driver returns a positive value from its attach method, indicating
that new firmware was loaded and the device will disconnect and
reconnect. The usb-serial core then skips the step of registering the
port devices; when the disconnect occurs, the attempt to unregister
the ports fails dramatically.
This problem shows up with Keyspan devices and it might affect others
as well.
When the attach method returns a positive value, the patch sets
num_ports to 0. This tells usb_serial_disconnect() not to try
unregistering any of the ports; instead they are cleaned up by
destroy_serial().

commit ec57935837a78f9661125b08a5d08b697568e040 upstream.
When probing the device in tpm_tis_init the call request_locality
uses timeout_a, which wasn't being initalized until after
request_locality. This results in request_locality falsely timing
out if the chip is still starting. Move the initialization to before
request_locality.
This probably only matters for embedded cases (ie mine), a BIOS likely
gets the TPM into a state where this code path isn't necessary.

[ Upstream commit 6ff9c2e7fa8ca63a575792534b63c5092099c286 ]
E100 places it's RX packet descriptors inside skb->data and uses them
with bidirectional streaming DMA mapping. Data in descriptors is
accessed simultaneously by the chip (writing status and size when
a packet is received) and CPU (reading to check if the packet was
received). This isn't a valid usage of PCI DMA API, which requires use
of the coherent (consistent) memory for such purpose. Unfortunately e100
chips working in "simplified" RX mode have to store received data
directly after the descriptor. Fixing the driver to conform to the API
would require using unsupported "flexible" RX mode or receiving data
into a coherent memory and using CPU to copy it to network buffers.
This patch, while not yet making the driver conform to the PCI DMA API,
allows it to work correctly on X86 with swiotlb (while not breaking
other architectures).

commit 96bcc722c47d07b6fd05c9d0cb3ab8ea5574c5b1 upstream
[SCSI] sr: report more accurate drive status after closing the tray.
So, what's happening here is that the drive is reporting a sense of
2/4/1 ("logical unit is becoming ready") from sr_test_unit_ready(), and
then we ask for the media event notification before checking that result
at all. The check_media_event_descriptor() call isn't getting a check
condition, but it's also reporting that the tray is closed and that
there's no media. In actuality it doesn't yet know if there's media or
not, but there's no way to express that in the media event status field.
My current thought is that if it told us the device isn't yet ready, we
should return that immediately, since there's nothing that'll tell us
any more data than that reliably:

commit 4d8d4d251df8eaaa3dae71c8cfa7fbf4510d967d upstream
[ cebbert@redhat.com: backport to 2.6.27 ]
Remove low_latency flag setting from nozomi and mxser drivers
The kernel oopses if this flag is set.
[and neither driver should set it as they call tty_flip_buffer_push from IRQ
paths so have always been buggy]

commit 2400a2bfbd0e912193fe3b077f492d4980141813 upstream
[ cebbert@redhat.com: backport to 2.6.27 ]
USB: removal of tty->low_latency hack dating back to the old serial code
This removes tty->low_latency from all USB serial drivers that push
data into the tty layer at hard interrupt context. It's no longer needed
and actually harmful.

commit 05ad709d04799125ed85dd816fdb558258102172 upstream
parport: quickfix the proc registration bug
Ideally we should have a directory of drivers and a link to the 'active'
driver. For now just show the first device which is effectively the existing
semantics without a warning.
This is an update on the original buggy patch that I then forgot to
resubmit. Confusingly it was proposed by Red Hat, written by Etched Pixels
fixed and submitted by Intel ...

This patch (as1272) changes the error code returned when an open call
for a USB device node fails to locate the corresponding device. The
appropriate error code is -ENODEV, not -ENOENT.

commit c15e3ca1d822abba78c00b1ffc3e7b382a50396e upstream.
Add a quirk entry for the Leading Driver UD-11 usb flash drive.
As Alan Stern told me, the device doesn't deal correctly with the
locking media feature of the device, and this patch incorporates it.
Compiled, tested, working.

converter cable
commit c47aacc67a3d26dfab9c9b8965975ed2b2010b30 upstream.
Attached patch adds USB vendor and product IDs for Bayer's USB to serial
converter cable used by Bayer blood glucose meters. It seems to be a
FT232RL based device and works without any problem with ftdi_sio driver
when this patch is applied. See: http://winglucofacts.com/cables/

commit 18753ebc8a98efe0e8ff6167afb31cef220c8e50 upstream.
access_ok() checks must be done on every part of the userspace structure
that is accessed. If access_ok() on one part of the struct succeeded, it
does not imply it will succeed on other parts of the struct. (Does
depend on the architecture implementation of access_ok()).
This changes the __get_user() users to first check access_ok() on the
data structure.

commit fef7cc0893146550b286b13c0e6e914556142730 upstream.
This patch adds two new device ids to the asix driver.
One comes directly from the asix driver on their web site, the other was
reported by Armani Liao as needed for the MSI X320 to get the driver to
work properly for it.
