Subject: drm/radeon: Update pitch for page flip
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8

Git-commit: c841e55274d67a9035f8f6263459280b5fcfdd4e
Patch-mainline: v5.15-rc1
References: jsc#PED-1166 jsc#PED-1168 jsc#PED-1170 jsc#PED-1218 jsc#PED-1220 jsc#PED-1222 jsc#PED-1223 jsc#PED-1225
When primary bo is updated, crtc's pitch may
have not been updated, this will lead to show
disorder content when user changes display mode,
we update crtc's pitch in page flip to avoid
this bug.
This refers to amdgpu's pageflip.
v1->v2:
Update all of the pitch in all of the page_flip functions
in radeon rather than just the evergreen one.
v2->v3:
Update pitch set method for r100 according to
radeon_legacy_crtc.c
