Subject: [PATCH] drm/i915: Hold the pps mutex across the whole panel power
 enable sequence
MIME-Version: 1.0
Content-Type: text/plain; charset=utf8
Content-Transfer-Encoding: 8bit

Just grab the pps_mutex once and do all the pps panel startup operations
while holding the mutex instead of grabbing the mutex separately for
each individual step.
