-Subject: [PATCH] drm/v3d: HACK: gut runtime pm for now.
-
-Something is still unstable -- on starting a new glxgears from an idle
-X11, I get an MMU violation in high addresses. The CTS also failed
-quite quickly. With this, CTS progresses for an hour before OOMing
-(allocating some big buffers when my board only has 600MB available to
-Linux)
