Subject: drm/amdgpu: Update pitch on page flips without DC as well
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8

Git-commit: 965ebe3d5d641925e0014a5a8c967fe579929b1d
Patch-mainline: v5.4-rc1
References: bsc#1152489

DC already handles this correctly since amdgpu minor version 31. Bump
the minor version again so that xf86-video-amdgpu can take advantage of
this working without DC as well now.
