From d36140c553925eecd978e388bc78d10af37eb90f Mon Sep 17 00:00:00 2001

Subject: [PATCH 4147/4736] 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, so drop it for runtime pm.
