Subject: [PATCH] drm/amdgpu: Update pitch on page flips without DC as well
From: Michel Dänzer <michel.daenzer at amd.com>
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.
