[PATCH 1/3] drm/msm: Fix race of GPU init vs timestamp power management.

We were using the same force-poweron bit in the two codepaths, so they could race to have one of them lose GPU power early. Signed-off-by: Eric Anholt Cc: sta...@vger.kernel.org # v5.9 --- drivers/gpu/drm/msm/adreno/a6xx_gmu.c | 25 ++--- drivers/gpu/drm/msm/adreno/a6xx_gmu.h
