drm/msm: Do rpm get sooner in the submit path
Unfortunately, due to an dev_pm_opp locking interaction with mm->mmap_sem, we need to do pm get before aquiring obj locks, otherwise we can have anger lockdep with the chain: opp_table_lock --> &mm->mmap_sem --> reservation_ww_class_mutex For an explicit fencing userspace, the impact should be minimal as we do all the fence waits before this point. It could result in some needless resumes in error cases, etc. Signed-off-by: Rob Clark <robdclark@chromium.org> Reviewed-by: Kristian H.
