2010-12-02[media] cx18: convert to unlocked_ioctlHans Verkuil1-1/+7
Also added locking around snd_cx18_pcm_ioctl as a precaution as requested by Andy Walls. Signed-off-by: Hans Verkuil <hverkuil@xs4all.nl> Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>

2010-02-26V4L/DVB: cx18: Fix memory leak in cx18-alsa starting of PCM capturesAndy Walls1-13/+5
The cx18_open_id is normally dynamically allocated and stored in the filp->private_data for v4l2 file operations. The cx18-alsa routines should not dynamically allocate a cx18_open_id because they never store it anywhere and never free it. This change fixes that and plugs a memory leak.

2010-02-26V4L/DVB: cx18: Add missing serialization locking to cx18-alsaAndy Walls1-1/+9
File operations that manipulate the state of the encoder, or video or audio subdevices or some of the stream flags need to be serialized. Add the serilization locks to cx18-alsa in a manner consistent with the locking for the v4l2 file operations.

2010-02-26V4L/DVB: cx18-alsa: Fix the rates definition and move some buffer freeing code.Devin Heitmueller1-10/+12
Clarify the rates available for the device, and move the freeing of the buffer to the free routine instead of the close (per Takashi's suggestion). Thanks to Takashi Iwai for reviewing and providing feedback. This work was sponsored by ONELAN Limited.

2010-02-26V4L/DVB: cx18-alsa: codingstyle cleanupDevin Heitmueller1-80/+76
Move the cx18_alsa_announce_pcm_data() function further up in the file, since apparently "make checkpatch" has never heard of a forward declaration. Note that despite the hg diff showing everything else as having been deleted/added, in reality it was only that one function that got moved (and the forward declaration was removed from the top of the file).

2010-02-26V4L/DVB: cx18-alsa: codingstyle cleanupDevin Heitmueller1-3/+5
Remove some dead code and make a PCM specific module debug parameter to avoid an extern reference. Signed-off-by: Devin Heitmueller <dheitmueller@kernellabs.com> Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>
2010-02-26V4L/DVB: cx18-alsa: codingstyle fixesDevin Heitmueller1-4/+4
Fix codingstyle issues, and make the minimum version for cx18-alsa required to be 2.6.17, so that we don't need all the #ifdefs related to the changes to ALSA structures.

2010-02-26V4L/DVB: cx18-alsa: fix memory leak in error conditionDevin Heitmueller1-0/+1
If the stream is already in use, make sure we free up the memory allocated earlier. Thanks to Andy Wall for reviewing and pointing this out. This work was sponsored by ONELAN Limited.

2010-02-26V4L/DVB: cx18-alsa: remove a couple of warningsDevin Heitmueller1-1/+0
Remove a couple of warnings from dead code during driver development. Signed-off-by: Devin Heitmueller <dheitmueller@kernellabs.com> Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>
2010-02-26V4L/DVB: cx18-alsa: name alsa device after the actual cardDevin Heitmueller1-1/+1
Use the cx18 board name in the ALSA description, to make it easier for users who run "arecord -l" to see which device they should be looking for. Also, use strlcpy() instead of strcpy().

2010-02-26V4L/DVB: cx18-alsa: remove unneeded debug lineDevin Heitmueller1-1/+0

2010-02-26V4L/DVB: cx18: overhaul ALSA PCM device handling so it worksDevin Heitmueller1-2/+241
Add code so that the PCM ALSA device actually works, and update the cx18-streams mechanism so that it passes the data off to the cx18-alsa module. This work was sponsored by ONELAN Limited.
