V4L: cx88-blackbird: fix vidioc_g_tuner never ending list of tuners

2007-08-04T16:10:26+00:00

v4l-info and other programs would loop indefinitely while querying the
tuners for cx88-blackbird cards.

The cause was that vidioc_g_tuner didn't return an error value for
qctrl->id != 0, making the application think there is a never ending
list of tuners...

This patch adds the same index check as done in vidioc_g_tuner() in
cx88-video.

V4L: bttv: fix v4l1 api usage breaking the driver

2007-08-04T16:10:26+00:00

If one uses a V4L *one* application, such as vlc or mplayer's v4l driver, as
the first user after the driver is loaded, the driver wedges itself and will
never capture properly.  Even if one uses a V4L2 application later, it still
won't work.

If one uses a V4L *two* application first, such as tvtime or mplayer's v4l2
driver, then the driver will be ok.  One can then run a V4L1 application, and
it will work.

It turns out the problem is with norm changing and the crop support that was
added in 2.6.21.  The driver defaults to PAL, and keeps the last norm it was
set too across opens.  If one changes the norm via V4L1, the cropping
parameters are not reset like they should be, and they'll remain broken across
device opens.

This patch removes the direct setting of btv->tvnorm in the V4L1 ioctl
VIDIOCSCHAN handler.  The norm is set via the existing call to set_input(),
which calls set_tvnorm(), which will reset the cropping values now that it is
able to detect the norm change.

saa7134: fix thread shutdown handling

2007-08-04T16:10:25+00:00

This patch changes the test for the thread pid from >= 0 to > 0.

When the saa7134 driver initialization fails after a certain point, it goes
through the complete shutdown process for the driver.  Part of shutting it
down includes tearing down the thread for tv audio.

The test for tearing down the thread tests for >= 0.  Since the dev
structure is kzalloc'd, the test will always be true if we haven't tried to
start the thread yet.  We end up waiting on pid 0 to complete, which will
never happen, so we lock up.

This bug was observed in Novell Bugzilla 284718, when request_irq() failed.

[PATCH] V4L/DVB (5593): Budget-ci: Fix tuning for TDM 1316 (160..200 MHz)

Petri Helin found that this changeset broke tuning:

'Well, after going through the changes that might have had effect on
tuning, I found out the one which had caused this problem. I do not know
the actual reason behind the change, but the changelog says that it
was meant to "Fix TD1316 tuner for DVBC". But at least in my case it
seams to have broken the tuner instead.'

DVB: dvb-usb-remote - fix oops when changing keymap

2007-04-14T01:35:39+00:00

DVB USB remotes do not support changing keycode maps but set
input_dev->keycodesize and input_dev->keycodemax without setting
input_dev->keycode. This causes kernel oops when user tries to
look up (or change) current keymap.

While the proper fix would be to make remotes handle keymap changes
we'll just remove keycodemax and keycodesize initialization so
EVIOCGKEYCODE and EVIOCSKEYCODE will simply return -EINVAL.

V4L/DVB (5496): Pluto2: fix incorrect TSCR register setting

2007-04-02T14:03:05+00:00

The ADEF bits in the TSCR register have different meanings in read and
write mode. For this reason ADEF has to be reset on every
read-modify-write operation.
This patch introduces a special write function for this register, which
takes care of it.

Thanks to Holger Magnussen for pointing my nose at this problem.

V4L/DVB (5495): Tda10086: fix DiSEqC message length

2007-04-02T14:03:04+00:00

Setting the message length to zero means to send one byte, so you need a
subtraction instead of an addition.
