drm/amdgpu: Fix uninitialized variable in gfxhub_v1_2_xcp_resume
drivers/gpu/drm/amd/amdgpu/gfxhub_v1_2.c:657:6: error: variable 'ret' is used uninitialized whenever 'if' condition is false [-Werror,-Wsometimes-uninitialized] if (!amdgpu_sriov_vf(adev)) ^~~~~~~~~~~~~~~~~~~~~~ drivers/gpu/drm/amd/amdgpu/gfxhub_v1_2.c:660:9: note: uninitialized use occurs here return ret; ^~~ drivers/gpu/drm/amd/amdgpu/gfxhub_v1_2.c:657:2: note: remove the 'if' if its condition is always true if (!amdgpu_sriov_vf(adev)) ^~~~~~~~~~~~~~~~~~~~~~~~~~~ drivers/gpu/drm/amd/amdgpu/gfxhub_v1_2.c:648:9: note: initialize the variable 'ret' to silence this warning int ret; ^ = 0 1 error generated.
