drivers/gpu/drm/amd/amdgpu/psp_v10_0.c: In function 'psp_v10_0_ring_stop':
drivers/gpu/drm/amd/amdgpu/psp_v10_0.c:230:19: warning:
 variable 'ring' set but not used [-Wunused-but-set-variable]

drivers/gpu/drm/amd/amdgpu/psp_v3_1.c: In function 'psp_v3_1_ring_stop':
drivers/gpu/drm/amd/amdgpu/psp_v3_1.c:359:19: warning:
