stable inclusion from stable-5.10.52 commit b3f8120039d5c33230e4a2cf5cbb30a91aa64bc3 bugzilla: 175542 https://gitee.com/openeuler/kernel/issues/I4DTKU
Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id=...
--------------------------------
commit 68b433fe6937cfa3f8975d18643d5956254edd6a upstream.
It should have been an OVERLAY from the beginning. The documentation stipulates that there should be an unique PRIMARY plane per CRTC.
