v4l2_prio_init/open/close returned an int when in fact they would
always return 0. Make these void functions.
v4l2_prio_close and v4l2_prio_check pass an enum v4l2_priority as a
pointer for no good reason. Replace with a normal enum v4l2_priority
argument.
These changes will simplify the work of moving priority handling into
the v4l core.

Due to obvious copy and paste coding a number of video capture drivers
which implement a limit on the buffer memory decremented the user
supplied buffer count in a while loop until it reaches an acceptable
value.
This is a silly thing to do when the maximum value can be directly
computed.

As reported by Randy Dunlap <randy.dunlap@oracle.com>:
drivers/staging/cx25821/cx25821-video.c:89:struct cx25821_fmt *format_by_fourcc(unsigned int fourcc)
(not static)
conflicts with (has the same non-static name as)
drivers/media/common/saa7146_video.c:87:struct saa7146_format* format_by_fourcc(struct saa7146_dev *dev, int fourcc)
To solve, add cx25821_ prefix to the exported functions found on cx25821-video.h.
This patch were generated by this little shell/perl script:

Now that the video_device registration is tested using
video_is_registered(), drivers don't need to initialize the
video_device::minor field to -1 anymore.
Remove those unneeded assignments.

Fix all device drivers to use the video_drvdata function instead of
maintaining a local list of minor to private data mappings. Call
video_set_drvdata to register the driver private pointer when not
already done.
Where applicable, the local list of mappings is completely removed when
it becomes unused.

Lindent caused some compilation breakages. There were also others
related to some other changes at kernel KABI.
There's still one missing warning fix against 2.6.30:
/home/v4l/cx25821/v4l/cx25821-alsa.c: In function 'cx25821_audio_initdev':
/home/v4l/cx25821/v4l/cx25821-alsa.c:706: warning: 'snd_card_new' is deprecated (declared at include/sound/core.h:306)

The original driver were generated with some dos editor, and used their
own coding style.
This patch does some automatic CodingStyle fixes, by running dos2unix
and Lindent tools.
More work still needs to be done for it to use upstream CodingStyle.
