I believe dcn20 could also receive the same treatment, as I'm still
getting a similar warning on display_mode_vba_20.c:
drivers/gpu/drm/amd/amdgpu/../display/dc/dml/dcn20/display_mode_vba_20.c:1085:13:

2 warnings generated.
To reproduce it on clang-14, you can run:
make -skj"$(nproc)" LLVM=1 LLVM_IAS=1 i386_defconfig
scripts/config -e DRM_AMDGPU
make -skj"$(nproc)" LLVM=1 LLVM_IAS=1 olddefconfig
drivers/gpu/drm/amd/amdgpu/../display/dc/dml/dcn20/display_mode_vba_20.o
I believe it is also reproducible on GCC.
