As previously fixed for dml in commit4769278e5c("amdgpu/dc/dml: Support clang option for stack alignment") and calcs in commitcc32ad8f55("amdgpu/dc/calcs: Support clang option for stack alignment"), dcn20 uses an option that is not available with clang: clang: error: unknown argument: '-mpreferred-stack-boundary=4' scripts/Makefile.build:281: recipe for target 'drivers/gpu/drm/amd/amdgpu/../display/dc/dcn20/dcn20_resource.o' failed Use the same trick that we have in the other two files.
