-Subject: [PATCH 0450/1050] drm/amdgpu: don't grab dev->struct_mutex in pm

-Similar to radeon, except that amdgpu doesn't even use struct_mutex to
-protect anything like the shared z buffer (sane gpu architecture,
-yay!). And the code already grabs the globa adev->ring_lock, so this
-code can't race with itself. Which makes struct_mutex completely
-redundnant. Remove it.
