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.
