Subject[PATCH 5.3 063/140] drm/komeda: Dont flush inactive pipes
Date
From: Mihail Atanassov <Mihail.Atanassov@arm.com>

[ Upstream commit b88639b8e3808c948169af390bd7e84e909bde8d ]

HW doesn't allow flushing inactive pipes and raises an MERR interrupt
if you try to do so. Stop triggering the MERR interrupt in the
middle of a commit by calling drm_atomic_helper_commit_planes
with the ACTIVE_ONLY flag.
