[PATCH 2/4] drm/atomic: Set all the changed flags in one place.

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

 



Now that handle_conflicting_encoders cannot disable crtc's any more
it makes sense to set all the changed flags in 1 place.
This makes the code slightly less magical.

The (now removed) comment is out of date. The only reason the
active_changed was set late was because handle_conflicting_encoders
could disable connectors. This is no longer the case,
and we can put everything in 1 place.
