Subject: [PATCH 0817/2940] drm/amdgpu: remove set but not used variable 'ring'
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Fixes gcc '-Wunused-but-set-variable' warning:

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:
 variable ‘ring’ set but not used [-Wunused-but-set-variable]

It not used since commit
