[PATCH 0/8] Port xf86-video-v4l driver to V4L2 version 2

[Mauro Carvalho Chehab]

This is the second version of my backport patches. To avoid spending
people's time on looking at lines that have only whitespace changes,
I broke the patch I submitted two days ago into two patches: 
the first one with just the logical changes, and the second one with
just CodingStyle (whitespace) fixes.

Reworking on a driver with whitespace and identation problems is hard,
as it makes harder for people to work with the source code.

So, the first two patches have basically the same content as the patch
I submitted earlier[1].

The fix patch I submited for xserver is still needed[2], otherwise
loading the v4l driver with a video driver that doesn't support overlay
will cause a server crash.

The remaining patches on this series fix some bugs found on the tests 
I made with:
	1) a Nvidia FX5200 and the nv driver, and a bttv Encore FM board;
	2) a Nvidia 6600 and nouveau driver, and a Kworld SBTV-D board
	  (to test it on an environment where Xv overlay is not available).
And by some tests made by Dmitry Butskoy with a bttv AVerMedia TVPhone98
board, with a Radeon RV100, using an old version of the Radeon driver.

As I said before, the intention now is to port it to work with textured
video. Help is wanted to point us how to use a textured video from the
v4l driver.

To make easier for people to test and review, the same patches are also
available on a git repository at:
	http://git.linuxtv.org/mchehab/xf86-video-v4l.git

PS.: I'm c/c just this  message to the media devel ML, for people there
     to be aware of the changes. There's not much sense to submit the
     remaining patches there.
