Subject: [PATCH -next] drm/amdgpu: remove set but not used variable
'grbm_soft_reset'
drivers/gpu/drm/amd/amdgpu/gfx_v8_0.c: In function
variable 'srbm_soft_reset' set but not used [-Wunused-but-set-variable]
drivers/gpu/drm/amd/amdgpu/gfx_v8_0.c: In function
variable 'srbm_soft_reset' set but not used [-Wunused-but-set-variable]
It never used since introduction in commit d31a501ead7f ("drm/amdgpu: add
pre_soft_reset ip func") and e4ae0fc33631 ("drm/amdgpu: implement
gfx8 post_soft_reset")
