The concurrent commit 78f0929884d4 ("powerpc/64: Always build with 128-bit long double") overrides the renaming change for the select in config DRM_AMD_DC, and this leads to selecting the non-existent DRM_AMD_DC_DCN. It is easy to fix, adjust this one line to the renaming and 'select DRM_AMD_DC_FP' once both commits are merged. For now, I am just reporting to let you know; probably, it is best to get a quick fix-up patch with -rc2, once all the changes landed in -rc1. Best regards, Lukas
