drm/amd/pm/swsmu: Avoid using structure_size uninitialized in smu_cmn_init_soft_gpu_metrics
Clang warns: drivers/gpu/drm/amd/amdgpu/../pm/swsmu/smu_cmn.c:764:2: warning: variable 'structure_size' is used uninitialized whenever switch default is taken [-Wsometimes-uninitialized] default: ^~~~~~~ drivers/gpu/drm/amd/amdgpu/../pm/swsmu/smu_cmn.c:770:23: note: uninitialized use occurs here memset(header, 0xFF, structure_size); ^~~~~~~~~~~~~~ drivers/gpu/drm/amd/amdgpu/../pm/swsmu/smu_cmn.c:753:25: note: initialize the variable 'structure_size' to silence this warning uint16_t structure_size; ^ = 0 1 warning generated. Return in the default case, as the size of the header will not be known.
