In-flight collision: DRM_AMD_DC_DCN renaming

[Lukas Bulwahn]

Dear Michael, dear Harry, dear Alex,

The commit 4652ae7a51b7 ("drm/amd/display: Rename DCN config to FP")
renames config DRM_AMD_DC_DCN to config DRM_AMD_DC_FP. 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
