Hi Mauro,

After merging the v4l-dvb tree, today's linux-next build (x86_64
allmodconfig) failed like this:

drivers/media/media-devnode.c:40:28: error: linux/smp_lock.h: No such file or directory

It got removed by this commit: 4ba8216cd90560bc402f52076f64d8546e8aefcb.

There's no reason for the header to be there at media-devnode.c, as it doesn't use
BKL.

Caused by commit cb3c186e31be ("[media] media: Media device node
support").  The BKL is no more ...

Why is a patch with Author date 2009-12-09 turning up in linux-next today?

Because the Media Controller stuff is under development since 2008, but it took a long
time to be mature enough to be merged.

I have used the v4l-dvb tree from next-20110321 for today.

The fix patch is as simple as the enclosed one. I'm folding it together with the
original changeset (cb3c186e31be), in order to avoid bisect issues.

Thanks!
Mauro
