V4L/DVB (10218): cx23885: Fix Oops for mixed install of analog and digital only cards

2009-03-23T21:55:26+00:00

commit cd8f894eacf13996d920fdd2aef1afc55156b191 upstream.

Analog support for HVR-1250 has not been completed, but does exist for
the HVR-1800.

Since both cards use the same driver, it tries to create the analog
dev for both devices, which is not possible.

This causes a NULL error to show up in video_open and mpeg_open.

-Mark

Iterations through the cx23885_devlist must check for NULL
pointers as some supported devices only have DVB support at the moment.
Mark Jenks encoutered an Oops in a system with both an HVR-1250 and HVR-1800
installed.

V4L: ivtv: fix decoder crash regression

2009-03-17T00:32:32+00:00

(cherry picked from commit ac9575f75c52bcb455120f8c43376b556acba048)

The video_ioctl2 conversion of ivtv in kernel 2.6.27 introduced a bug
causing decoder commands to crash. The decoder commands should have been
handled from the video_ioctl2 default handler, ensuring correct mapping
of the argument between user and kernel space. Unfortunately they ended
up before the video_ioctl2 call, causing random crashes.

Thanks to hannes@linus.priv.at for testing and helping me track down the
cause!

V4L: saa7127: fix broken S-Video with saa7129

2009-03-17T00:32:32+00:00

(backported from commit 0f3559ef17362a7dd5017521a4dd4cad31263395)

Register 0x2d has to be set differently in the saa7129 compared to the
saa7127. This was not done correctly, so S-Video was broken in certain
circumstances.

This fixes a regression introduced in 2.6.28.

V4L: tda8290: fix TDA8290 + TDA18271 initialization

2009-03-17T00:32:31+00:00

(cherry picked from commit 439b72b69e4992e9ec34b74304f0fa95623934eb)

Don't call tda8290_init_tuner unless we have either a TDA8275 or TDA8275A
present. Calling this function will cause a TDA18271 to get sick, so we
should only call it when needed.

DVB: s5h1409: Perform s5h1409 soft reset after tuning

2009-03-17T00:32:31+00:00

(cherry picked from commit 67e70baf043cfdcdaf5972bc94be82632071536b)

Just like with the s5h1411, the s5h1409 needs a soft-reset in order for it
to know that the tuner has been told to change frequencies.  This change
changes the behavior from "random tuning times between 500ms to complete
tuning lock failures" to "tuning lock consistently within 700ms".

Thanks to Robert Krakora  for doing
initial testing of the patch on the KWorld 330U.

Thanks to Andy Walls  for doing testing of the patch on
the HVR-1600.

Thanks to Michael Krufky  for doing additional testing.

V4L/DVB (9920): em28xx: fix NULL pointer dereference in call to VIDIOC_INT_RESET command

2008-12-23T11:13:50+00:00

Fix a NULL pointer dereference that would occur if the video decoder tied to
the em28xx supports the VIDIOC_INT_RESET call (for example: the cx25840 driver)

V4L/DVB (9906): v4l2-compat: test for unlocked_ioctl as well.

2008-12-16T18:43:59+00:00

The v4l_compat_ioctl32() function only tested for the presence of the
ioctl op, not for unlocked_ioctl. So it would always return an error
when used with drivers that use unlocked_ioctl instead of ioctl.

V4L/DVB (9885): drivers/media Kconfig's: fix bugzilla #12204

2008-12-16T18:43:59+00:00

When the tuner modules were moved to common/tuners, a separate customize
option were added for tuners. However, the automatic selection of the
tuners were still using the older option.

This causes that the automatic selection to fail, if DVB_FE_CUSTOMISE is
selected. Also, since those tuners are now under MEDIA_TUNER_CUSTOMIZE
menu, if you unset MEDIA_TUNER_CUSTOMIZE, you can't manually select the
tuners.

This patch fixes this error by replacing DVB_FE_CUSTOMISE by
MEDIA_TUNER_CUSTOMIZE on all places were a tuner is selected.

The patch were generated by this small script:

for i in `find drivers/media -name Kconfig`; do
  cat $i|perl -ne 's/(MEDIA_TUNER.*)DVB_FE_CUSTOMISE/\1MEDIA_TUNER_CUSTOMIZE/; print $_' >a
  mv a $i
done

Also, manually reordered the tuner entries.

V4L/DVB (9781): [PATCH] Cablestar 2 I2C retries (fix CableStar2 support)

2008-12-16T18:43:58+00:00

At some point the Flexcop driver was changed to support newer Flexcop cards.
These modifications however broke the detection of Cablestar 2 DVB-C cards.

The reason is that the earlier version of the driver used to retry
unsuccessful i2c operations. The demodulator of Cablestar 2 cards (stv0297)
seems to be very dependent on these retries and adding them back fixes
Cablestar detection.

This patch restores this behaviour for the CableStar2.
