[GIT PATCHES FOR 3.1] Control event and control framework

[Hans Verkuil]

Hi Mauro,

This is the pull request containing all control event and control framework
patches. The first set (until the compat-ioctl32 patch) you have already reviewed.

The second set contains the RFCv2 patch series posted Tuesday together with
the two changes you wanted for the first set ('make manual_mode_value 8 bits'
and 'V4L2_EVENT_SUB_FL_ALLOW_FEEDBACK').

There were no comments regarding the RFCv2 patch series, so that is unchanged.

The first 18 patches are also part of the pull request I posted on Tuesday, you
can either pull from that request first and than this one, or just pull it all
from this repository, whatever is easiest for you.

Of course, the poll() changes are not included, that is still under discussion.

Regards,

	Hans
