[PATCH] drm/msm/mdp5: don't use autosuspend
From: Rob Clark
Date: Fri Oct 20 2017 - 08:19:02 EST
It's only likely to paper over bugs. Unlike the gpu, where we want to
keep things alive a bit longer in expectation of the next frame's
submit, when the display is shut down we can power off immediately.
