stable inclusion
from stable-v5.10.165
commit a3ef532483993985b47bed76e0fbb8ff1f8fad30
category: bugfix
bugzilla: https://gitee.com/openeuler/kernel/issues/I7T7G4

Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id=a3ef532483993985b47bed76e0fbb8ff1f8fad30



--------------------------------

commit 040625ab upstream.

[Why]
Setting scaling does not correctly update CRTC state. As a result
dc stream state's src (composition area) && dest (addressable area)
was not calculated as expected. This causes set scaling doesn's work.

[How]
Correctly update CRTC state when setting scaling property.
