I'm not quite sure of how I should do this, so I will describe as much
as possible. Please feel free to tell me how I should have done it so I
know for next time!

The patch when running

make kernel-links KDIR=/path/to/kernel

fails with the following "linux/include/linux/videodev.h.rej" file:

*** 1,6 ****
  #ifndef __LINUX_VIDEODEV_H
  #define __LINUX_VIDEODEV_H

  #include <linux/types.h>

  #define HAVE_V4L1 1
--- 1,7 ----
  #ifndef __LINUX_VIDEODEV_H
  #define __LINUX_VIDEODEV_H

+ #include "compat.h"
  #include <linux/types.h>

  #define HAVE_V4L1 1

The reason that this fails is that there is an additional line "#ifdef
CONFIG_VIDEO_V4L1_COMPAT" before "#define HAVE_V4L1 1" which is not in
the patch, and linux/types.h has changed to linux/videodev2.h . IE:


#include <linux/videodev2.h>

#define HAVE_V4L1 1

I'm not sure how to make a patch, so here is my first attempt:

$  diff -u -p v4l/scripts/makelinks.sh_OLD  v4l/scripts/makelinks.sh
--- v4l/scripts/makelinks.sh_OLD        2006-08-04 10:50:42.000000000 +0100

  #define __LINUX_VIDEODEV_H

+#include "compat.h"
- #include <linux/types.h>
+ #include <linux/videodev2.h>

  #define HAVE_V4L1 1

With this patch I now get:

patching file linux/include/linux/videodev.h
Hunk #1 succeeded at 12 (offset 11 lines).

Which looks good to me?

I hope that this helps. You are all doing sterling work, thank you so
much. I use your drivers daily, on my MythTV box, and if it wasn't for
you guys my stress levels would probably be higher due to less time
spent vegging out in front of it. Thanks again. :)
