Subject: RE: [PATCH 2/5] drm/amdgpu: move gpu reset out of amdgpu_device_suspend
It seems amdgpu_pmops_runtime_suspend() needs to be updated accordingly also.

Subject: [PATCH 2/5] drm/amdgpu: move gpu reset out of amdgpu_device_suspend
Move it into the caller. There are cases were we don't want it. We need it for hibernation, but we don't need it for runtime pm.
