From: Arnd Bergmann <arnd@xxxxxxxx> As the DRM_AMD_DC_DCN3_0 code was x86-only and fails to build on arm64, merging it into DRM_AMD_DC means that the top-level symbol is now x86-only as well. Compilation fails on arm64 with clang-12 with drivers/gpu/drm/amd/amdgpu/../display/dc/dml/dcn30/display_mode_vba_30.c:3641:6: error: stack frame size of 2416 bytes in function 'dml30_ModeSupportAndSystemConfigurationFull' [-Werror,-Wframe-larger-than=] void dml30_ModeSupportAndSystemConfigurationFull(struct display_mode_lib *mode_lib) I tried to see if the stack usage can be reduced, but this is code that is described as "This file is gcc-parsable HW gospel, coming straight from HW engineers." and is written in a way that is inherently nonportable and not meant to be understood by humans. There are probably no non-x86 users of this code, so simplify the dependency list accordingly.
