+Subject: [PATCH 4748/5725] drm/amdgpu: Use correct enum to set powergating
+ state
+
+Use enum amd_powergating_state instead of enum amd_clockgating_state.
+The underlying value stays the same, so there is no functional change
+in practise. This fixes a warning seen with clang:
+drivers/gpu/drm/amd/amdgpu/amdgpu_device.c:1930:14: warning: implicit
+ conversion from enumeration type 'enum amd_clockgating_state' to
+ different enumeration type 'enum amd_powergating_state'
+ [-Wenum-conversion]
+ AMD_CG_STATE_UNGATE);
+ ^~~~~~~~~~~~~~~~~~~
