Subject: [PATCH 1107/1110] drm/amdgpu: fix UVD enabled display after system
resume
During a playback using hardware decode (vdpau/vaapi), if the
system enters suspend and resumes back, the output of sysfs
entry amdgpu_pm_info displays UVD as being disabled. It is
confirmed from the output of ps and top commands that UVD is
actually engaged even after system resume.
This patch fixes the issue and the amdgpu_pm_info correctly
reports UVD being enabled after system resume.
