[PATCH AUTOSEL 5.5 12/66] drm/msm/mdp5: rate limit pp done timeout warnings

[Sasha Levin]

From: Brian Masney <masneyb@xxxxxxxxxxxxx>

[ Upstream commit ef8c9809acb0805c991bba8bdd4749fc46d44a98 ]

Add rate limiting of the 'pp done time out' warnings since these
warnings can quickly fill the dmesg buffer.
