+Subject: [PATCH 0495/1110] drm/amdgpu: add a new set of rlc function pointers
+
+Different asics tend to have different ways to interact
+with the RLC.  This just covers enter/exit of safe mode
+for updating CG and PG state, but could be extended to
+cover other RLC operations in the future if necessary.
