commit f1a4914bd04911fbeaee23445112adae8977144a upstream.
Added id, bindings and comments for Holtek USB ID 04d9:a072
LEETGION Hellion Gaming mouse to use the same corrections of the report
descriptor as Holtek 04d9:a067. As the mouse exceed HID_MAX_USAGES at the
same offsets in the reported descriptor.
Tested on the hardware.

commit 124df926090b32a998483f6e43ebeccdbe5b5302 upstream.
Remove the certificate date checks that are performed when a certificate is
parsed. There are two checks: a valid from and a valid to. The first check is
causing a lot of problems with system clocks that don't keep good time and the
second places an implicit expiry date upon the kernel when used for module
signing, so do we really need them?

commit 9736a89dafe07359d9c86bf9c3b815a250b354bc upstream.
Dynamic static allocation is evil, as Kernel stack is too low, and
compilation complains about it on some archs:
drivers/media/dvb-frontends/s5h1420.c:851:1: warning: 's5h1420_tuner_i2c_tuner_xfer' uses dynamic stack allocation [enabled by default]
Instead, let's enforce a limit for the buffer.
In the specific case of this frontend, only ttpci uses it. The maximum
number of messages there is two, on I2C read operations. As the logic
can add an extra operation, change the size to 3.

Instead, let's enforce a limit for the buffer. Considering that I2C
transfers are generally limited, and that devices used on USB has a
max data length of 64 bytes for the control URBs.
So, it seem safe to use 64 bytes as the hard limit for all those devices.
On most cases, the limit is a way lower than that, but this limit
is small enough to not affect the Kernel stack, and it is a no brain
limit, as using smaller ones would require to either carefully each
driver or to take a look on each datasheet.

commit 56ac033725ec93a45170caf3979eb2b1211a59a8 upstream.
Dynamic static allocation is evil, as Kernel stack is too low, and
compilation complains about it on some archs:
drivers/media/tuners/tuner-xc2028.c:651:1: warning: 'load_firmware' uses dynamic stack allocation [enabled by default]
Instead, let's enforce a limit for the buffer.
In the specific case of this driver, the maximum limit is 80, used only
on tm6000 driver. This limit is due to the size of the USB control URBs.
Ok, it would be theoretically possible to use a bigger size on PCI
devices, but the firmware load time is already good enough. Anyway,
if some usage requires more, it is just a matter of also increasing
the buffer size at load_firmware().

commit 24e9a47e14f0a97ee97abc3dd86b2ef254448a17 upstream.
Dynamic static allocation is evil, as Kernel stack is too low, and
compilation complains about it on some archs:
drivers/media/v4l2-core/v4l2-async.c:238:1: warning: 'v4l2_async_notifier_unregister' uses dynamic stack allocation [enabled by default]
Instead, let's enforce a limit for the buffer.
In this specific case, there's a hard limit imposed by V4L2_MAX_SUBDEVS,
with is currently 128. That means that the buffer size can be up to
128x8 = 1024 bytes (on a 64bits kernel), with is too big for stack.
Worse than that, someone could increase it and cause real troubles.
So, let's use dynamically allocated data, instead.

That happens because the routine allocates 256 bytes for an eeprom buffer, plus
the size of struct i2c_client, with is big.
Change the logic to dynamically allocate/deallocate space for struct i2c_client,
instead of using the stack.

commit 2ba3154d9cb13697b97723cce75633b48adfe826 upstream.
The PL061 driver had the irqdomain initialization in an unfortunate
place: when used with device tree (and thus passing the base IRQ
0) the driver would work, as this registers an irqdomain and waits
for mappings to be done dynamically as the devices request their
IRQs, whereas when booting using platform data the irqdomain core
would attempt to allocate IRQ descriptors dynamically (which works
fine) but also to associate the irq_domain_associate_many() on all
IRQs, which in turn will call the mapping function which at this
point will try to set the type of the IRQ and then tries to acquire
a non-initialized spinlock yielding a backtrace like this:

This moves the irqdomain initialization to a point where the spinlock
and GPIO chip are both fully propulated, so the callbacks can be used
without crashes.
I had some problem reproducing the crash, as the devm_kzalloc():ed
zeroed memory would seemingly mask the spinlock as something OK,
but by poisoning the lock like this:
u32 *dum;
dum = (u32 *) &chip->lock;
*dum = 0xaaaaaaaaU;
I could reproduce, fix and test the patch.

commit d4b1bba76171cb783e32441b28462fe841073ed8 upstream.
Most of the hid sensor field size is reported in report_size field
in the report descriptor. For rotation fusion sensor the quaternion
data is 16 byte field, the report size was set to 4 and report
count field is set to 4. So the total size is 16 bytes. But the current
driver has a bug and not taking account for report count field. This
causes user space to see only 4 bytes of data sent via IIO interface.
The number of bytes in a field needs to take account of report_count
field. Need to multiply report_size and report_count to get total
number of bytes.

commit 26b818511c6562ce372566c219a2ef1afea35fe6 upstream.
In some platforms, specially Thinkpad series, rts5249 won't be
initialized properly. So we need adjust some phy parameters to
improve the compatibility issue.
It is a little different between simulation and real chip. We have
no idea about which configuration is better before tape-out. We set
default settings according to simulation, but need to tune these
parameters after getting the real chip.
I can't explain every change in detail here. The below information is
just a rough description:
PHY_REG_REV: Disable internal clkreq_tx, enable rx_pwst
PHY_BPCR: No change, just turn the magic number to macro definitions
PHY_PCR: Change OOBS sensitivity, from 60mV to 90mV
PHY_RCR2: Control charge-pump current automatically
PHY_FLD4: Use TX cmu reference clock
PHY_RDR: Change RXDSEL from 30nF to 1.9nF
PHY_RCR1: Change the duration between adp_st and asserting cp_en from
0.32 us to 0.64us
PHY_FLD3: Adjust internal timers
PHY_TUNE: Fine tune the regulator12 output voltage

commit 95d50b6c5e18ff7351c5f2a6ff53afaed5f7e664 upstream.
Certain devices with class HID, protocol None did not work with the HID
driver at one point, and as a result were bound to usbtouchscreen
instead as of commit 139ebe8 ("Input: usbtouchscreen - fix eGalax HID
ignoring"). This change was prompted by the following report:
https://lkml.org/lkml/2009/1/25/127
Unfortunately, the device mentioned in this report is no longer
available for testing.
We've recently discovered that some devices with class HID, protocol
None do not work with usbtouchscreen, but do work with usbhid. Here is
the report that made this evident:
http://comments.gmane.org/gmane.linux.kernel.input/31710
Driver binding for these devices has flip-flopped a few times, so both
of the above reports were regressions.
This situation would appear to leave us with no easy way to bind every
device to the right driver. However, in my own testing with several
devices I have not found a device with class HID that does not work with
the current HID driver. It is my belief that changes to the HID driver
since the original report have likely fixed the issue(s) that made it
unsuitable at the time, and that we should prefer it over usbtouchscreen
for these devices. In particular, HID quirks affecting these devices
were added/removed in the following commits since then:
fe6065d HID: add multi-input quirk for eGalax Touchcontroller
77933c3 Merge branch 'egalax' into for-linus
ebd11fe HID: Add quirk for eGalax touch controler.
d34c4aa HID: add no-get quirk for eGalax touch controller
This patch makes the HID driver no longer ignore eGalax/D-Wav/EETI
devices with class HID. If there are in fact devices with class HID
that still do not work with the HID driver, we will see another round of
regressions. In that case I propose we investigate why the device is
not working with the HID driver rather than re-introduce regressions for
functioning HID devices by again binding them to usbtouchscreen.
The corresponding change to usbtouchscreen will be made separately.

commit 92eb77d0ffbaa71b501a0a8dabf09a351bf4267f upstream.
evdev always tries to allocate the event buffer for clients using
kzalloc rather than vmalloc, presumably to avoid mapping overhead where
possible. However, drivers like bcm5974, which claims support for
reporting 16 fingers simultaneously, can have an extraordinarily large
buffer. The resultant contiguous order-4 allocation attempt fails due
to fragmentation, and the device is thus unusable until reboot.
Try kzalloc if we can to avoid the mapping overhead, but if that fails,
fall back to vzalloc.

commit 2ded3e5b61d61d0bc90bebb8004db6184c7db6eb upstream.
The current generic parser assumes blindly that the volume and mute
amps are found in the aamix node itself. But on some codecs,
typically Analog Devices ones, the aamix amps are separately
implemented in each leaf node of the aamix node, and the current
driver can't establish the correct amp controls. This is a regression
compared with the previous static quirks.
This patch extends the search for the amps to the leaf nodes for
allowing the aamix controls again on such codecs.
In this implementation, I didn't code to loop through the whole paths,
since usually one depth should suffice, and we can't search too
deeply, as it may result in the conflicting control assignments.

commit ced4cefc75fdb8be95eaee325ad0f6b2fc0a484b upstream.
When a headphone jack is configurable as input, the generic parser
tries to make it retaskable as Headphone Mic. The switching can be
done smoothly if Capture Source control exists (i.e. there is another
input source). Or when user explicitly enables the creation of jack
mode controls, "Headhpone Mic Jack Mode" will be created accordingly.
However, if the headphone mic is the only input source, we have to
create "Headphone Mic Jack Mode" control because there is no capture
source selection. Otherwise, the generic parser assumes that the
input is constantly enabled, thus the headphone is permanently set
as input. This situation happens on the old MacBook Airs where no
input is supported properly, for example.
This patch fixes the problem: now "Headphone Mic Jack Mode" is created
when such an input selection isn't possible.
