Currently the module init function registers a platform_device and
only then allocates its IRQ and I/O region. This allows allocation to
race with the device's suspend() function. Instead, allocate
resources in the platform driver's probe() function and free them in
the remove() function.
The module exit function removes the platform device before the
character device that provides access to it. Change it to reverse the
order of initialisation.

The function setup_vpif_input_channel_mode() used the VSCLKDIS register
instead of VIDCLKCTL. This meant that when in HD mode videoport channel 0
used a different clock from channel 1.
Clearly a copy-and-paste error.

2d3cbf8b (cgroup_freezer: update_freezer_state() does incorrect state
transitions) removed is_task_frozen_enough and replaced it with a simple
frozen call. This, however, breaks freezing for a group with stopped tasks
because those cannot be frozen and so the group remains in CGROUP_FREEZING
state (update_if_frozen doesn't count stopped tasks) and never reaches
CGROUP_FROZEN.
Let's add is_task_frozen_enough back and use it at the original locations
(update_if_frozen and try_to_freeze_cgroup). Semantically we consider
stopped tasks as frozen enough so we should consider both cases when
testing frozen tasks.
Testcase:
mkdir /dev/freezer
mount -t cgroup -o freezer none /dev/freezer
mkdir /dev/freezer/foo
sleep 1h &
pid=$!
kill -STOP $pid
echo $pid > /dev/freezer/foo/tasks
echo FROZEN > /dev/freezer/foo/freezer.state
while true
do
cat /dev/freezer/foo/freezer.state
[ "`cat /dev/freezer/foo/freezer.state`" = "FROZEN" ] && break
sleep 1
done
echo OK

Commit ede676c72d ("[...] add digital support for PV SBTVD hybrid")
added "select MEDIA_TUNER_NXP18271" to the VIDEO_CX231XX_DVB Kconfig
entry. But there's no Kconfig symbol MEDIA_TUNER_NXP18271. That should
have been MEDIA_TUNER_TDA18271. (The code added in that commit uses
tda18271_attach, which is only available if MEDIA_TUNER_TDA18271 is
set.)
The selects of MEDIA_TUNER_XC5000 and MEDIA_TUNER_TDA18271 should only
be done if MEDIA_TUNER_CUSTOMISE isn't set.

There's one comment that has been copied from bttv to many other
media/video drivers:
/* init + register i2c algo-bit adapter */
Meanwhile, many drivers use hardware I2C implementations instead of
relying on i2c-algo-bit, so this comment is misleading. Remove the
reference to "algo-bit" from all drivers, to avoid any confusion. This
is the best way to ensure that the comments won't go out of sync
again. Anyone interested in the implementation details would rather
look at the code itself.

Smatch complains that the wrong limiter is used here:
drivers/media/dvb/ttpci/av7110.c +906 dvb_feed_start_pid(12)
error: buffer overflow 'npids' 5 <= 19
Here is the problem code:
905 i = dvbdmxfeed->pes_type;
906 npids[i] = (pid[i]&0x8000) ? 0 : pid[i];
"npids" is a 5 element array declared on the stack. If
dvbdmxfeed->pes_type is more than 4 we probably put a (u16)0 past
the end of the array.
If dvbdmxfeed->pes_type is over 4 the rest of the function doesn't
do anything. dvbdmxfeed->pes_type is capped at less than
DMX_TS_PES_OTHER (20) in the caller function, but I changed it to
less than or equal to DMX_TS_PES_PCR (4).
