drm/amd/display: Do not add '-mhard-float' to dcn2{1,0}_resource.o for clang
This patch is for linux-5.15.y and earlier only. It is functionally equivalent to upstream commit 7db038d9790e ("drm/amd/display: Do not add '-mhard-float' to dml_ccflags for clang"), which was created after all files that require '-mhard-float' were moved under the dml folder. In kernels older than 5.18, which do not contain upstream commits 22f87d998326 ("drm/amd/display: move FPU operations from dcn21 to dml/dcn20 folder") cf689e869cf0 ("drm/amd/display: move FPU-related code from dcn20 to dml folder") newer versions of clang error with clang: error: unsupported option '-mhard-float' for target 'x86_64-linux-gnu' make[6]: *** [scripts/Makefile.build:289: drivers/gpu/drm/amd/amdgpu/../display/dc/dcn20/dcn20_resource.o] Error 1 clang: error: unsupported option '-mhard-float' for target 'x86_64-linux-gnu' make[6]: *** [scripts/Makefile.build:289: drivers/gpu/drm/amd/amdgpu/../display/dc/dcn21/dcn21_resource.o] Error 1 Apply a functionally equivalent change to prevent adding '-mhard-float' with clang for these files.
