[GIT PATCHES FOR 3.1] Add Control Event and autofoo/foo support

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Hi Mauro,

This is the same as the first pull request, except for:

- the poll patch has been removed (to be discussed further)
- the corresponding poll changes in ivtv were removed (pending same
  discussion).
- a new patch has been added that fixes your manual_mode_value comments.

Note that I have left out the 'event feedback' fix in this patch series.
I'm going to make a patch for the second patch series instead: it's much
easier to implement there (that may have been a reason why I didn't
implement such a flag in the first place). I'll post that fix later for
review.

Regards,

        Hans
