Subject: [PATCH 2/4] drm/atomic: Set all the changed flags in one place.
Date: Thu,  6 Apr 2017 13:19:01 +0200	[thread overview]
Message-ID: <1491477543-31257-3-git-send-email-maarten.lankhorst@linux.intel.com> (raw)
In-Reply-To: <1491477543-31257-1-git-send-email-maarten.lankhorst@linux.intel.com>

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The (now removed) comment is out of date.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.
