commit 806b07c29b711aaf90c81d2a19711607769f8246 upstream.
IR support on FusionHDTV cards is broken since kernel 2.6.31. One side
effect of the switch to the standard binding model for IR I2C devices
was to let i2c-core do the probing instead of the ir-kbd-i2c driver.
There is a slight difference between the two probe methods: i2c-core
uses 0-byte writes, while the ir-kbd-i2c was using 0-byte reads. As
some IR I2C devices only support reads, the new probe method fails to
detect them.
For now, revert to letting the driver do the probe, using 0-byte
reads. In the future, i2c-core will be extended to let callers of
i2c_new_probed_device() provide a custom probing function.

commit 5c331fc8c19e181bffab46e9d18e1637cdc47170 upstream.
Fix ULE decapsulation bug when less than 4 bytes of ULE SNDU is packed
into the remaining bytes of a MPEG2-TS frame
ULE (Unidirectional Lightweight Encapsulation RFC 4326) decapsulation
code has a bug that incorrectly treats ULE SNDU packed into the
remaining 2 or 3 bytes of a MPEG2-TS frame as having invalid pointer
field on the subsequent MPEG2-TS frame.

commit 19f48cb105b7fa18d0dcab435919a3a29b7a7c4c upstream.
this patch fixes a memory leak which occurs when an em28xx card with DVB
extension is unplugged or its DVB extension driver is unloaded. In
dvb_fini(), dev->dvb must be freed before being set to NULL, as is done
in dvb_init() in case of error.
Note that this bug is also present in the latest stable kernel release.

invalid Payload Pointer
commit 29e1fa3565a7951cc415c634eb2b78dbdbee151d upstream.
ULE (Unidirectional Lightweight Encapsulation RFC 4326) decapsulation
has a bug that causes endless loop when Payload Pointer of MPEG2-TS
frame is 182 or 183. Anyone who sends malicious MPEG2-TS frame will
cause the receiver of ULE SNDU to go into endless loop.
This patch was generated and tested against linux-2.6.32.9 and should
apply cleanly to linux-2.6.33 as well because there was only one typo
fix to dvb_net.c since v2.6.32.
This bug was brought to you by modern day Santa Claus who decided to
shower the satellite dish at Keio University with heavy snow causing
huge burst of errors. We, receiver end, received Santa Claus's gift in
the form of kernel bug.
Care has been taken not to introduce more bug by fixing this bug, but
please scrutinize the code for I always produces buggy code.

UHCI controllers
commit 70136081fc67ea77d849f86fa323e5773c8e40ea upstream.
If you read the mail to Oliver Neukum on the linux-usb list, then you know
that I found a cure for the mysterious problem that the MR97310a CIF "type
1" cameras have been freezing up and refusing to stream if hooked up to a
machine with a UHCI controller.
Namely, the cure is that if the camera is an mr97310a CIF type 1 camera, you
have to send it 0xa0, 0x00. Somehow, this is a timing reset command, or
such. It un-blocks whatever was previously stopping the CIF type 1 cameras
from working on the UHCI-based machines.

commit 2434466432464110b5307757e0285dd41f15512e upstream.
Move I2C IR initialization from just after I2C bus setup to right
before non-I2C IR initialization. This avoids the case where an I2C IR
device is blocking audio support (at least the PV951 suffers from
this). It is also more logical to group IR support together,
regardless of the connectivity.
This fixes bug #15184:

constant => sizeof conversion.
commit 53f68607caba85db9a73846ccd289e4b7fa96295 upstream.
Regression was caused by my commit 6b35ca0d3d586b8ecb8396821af21186e20afaf0
which determined message size using sizeof rather than hardcoded constants.
Unfortunately pwc_set_shutter_speed reuses a 2 byte buffer for a one byte
message too so the sizeof was bogus in this case.
All other uses of sizeof checked and are ok.

commit c1db53b36633e6a7511dbec7c372f01a31528f0c upstream.
I'm trying to fix it on the GCC side (PR43007), but the module is
quite stupid in using ULL constants to operate on u32 values:
static int apply_frontend_param (struct dvb_frontend* fe, struct
dvb_frontend_parameters *param)
{
...
static const u32 ppm = 8000;
u32 spi_bias;
...
spi_bias *= 1000ULL;
spi_bias /= 1000ULL + ppm/1000;
which causes current GCC 4.5 to emit calls to __udivdi3 for i?86 again.
This patch fixes this issue.

commit 691c9ae099b9bcb5c27125af00a4a90120977458 upstream.
A DVB demultiplexer device can be used to set up either a PES filter or
a section filter. In the former case, the ts field of the feed union of
struct dmxdev_filter is used, in the latter case the sec field of the
same union is used.
The ts field is a struct list_head, and is currently initialized in the
open() method of the demux device. When for a given demuxer a section
filter is set up, the sec field is played with, thus if a PES filter
needs to be set up after that the ts field will be corrupted, causing a
kernel oops.
This fix moves the list head initialization to
dvb_dmxdev_pes_filter_set(), so that the ts field is properly
initialized every time a PES filter is set up.

This solves a problem in firedtv that has become major for Swedish DVB-T
users the last month or so. It will most likely solve issues seen by
other users as well.
If the length of an AVC message is greater than 127, the length field
should be encoded in LV mode instead of V mode. V mode can only be used
if the length is 127 or less. This patch ensures that the CA_PMT
message is always encoded in LV mode so PMT message of greater lengths
can be supported.

waiting processes
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.
