Subject: [PATCH] drm/i915: move encoder->mode_set calls to crtc_mode_set
Date: Wed, 31 Oct 2012 19:26:13 +0100
Message-ID: <1351707973-1049-1-git-send-email-daniel.vetter@ffwll.ch> (raw)
In-Reply-To: <b94cdc$6u9lla@fmsmga001.fm.intel.com>

Makes more sense to group the entire mode_set stage into one function.
Noticed while discussiing the rather confusing set of function names
with Paulo Zanoni. Unfortunately I don't have an idea to make the
function names lesss confusion.

v2: Use for_each_encoder_on_crtc as suggested by Chris Wilson.
