The patch is against -hg tree. So, the patch is correct. However, I've already committed a backout patch at the tree. Probably, -hg will merge this correctly.

Cheers,

These changes should appear in the next update of the v4l2spec.

HCENTER and VCENTER are unused in the tree so I added a _DEPRECATED postfix so applications can remove their use.

You should use "make commit". It calls some scripts that strips bad whitespaces, checks CodingStyle violations, re-generates Documentation/video4linux/CARDLIST.*, ...

The patch above has one intesting thing: it checks for merge conflicts. Maybe we can add this also to make commit scripts.

Add all of the recently proposed camera class controls. These controls should appear in the next version of the v4l2spec.
