Hello devs,
While building the -next tree with allyesconfig and GCC 16, I got this
build error:
drivers/gpu/drm/amd/amdgpu/amdgpu_vcn.h:164:26: error: variable
‘internal_reg_offset’ set but not used [-Werror=unused-but-set-variable=]

The WREG32_SOC24_DPG_MODE macro is calling the SOC24_DPG_MODE_OFFSET.
The variable internal_reg_offset, while not being used in
SOC24_DPG_MODE_OFFSET, is used in WREG32_SOC24_DPG_MODE. I might be
wrong though. So I'm wondering is there any *easy* way to fix this?
