drm/msm/mdp5: restore cursor state when enabling crtc Since we enabled runtime PM, we cannot count on cursor registers to retain their values. This can result in situations where we think the cursor is enabled when we enable the CRTC but it is trying to scan out null (and the rest of cursor position/size is lost), resulting in faults and generally angering the hw when coming out of DPMS with a cursor enabled. stable backport note: reverting 774e39ee3572 is also a suitable fix Fixes: 774e39ee3572 drm/msm/mdp5: Set up runtime PM for MDSS Signed-off-by: Rob Clark <robdclark@gmail.com> Reviewed-by: Archit Taneja <architt@codeaurora.org>
