stable inclusion
from stable-v5.10.115
commit 93a1f0755edc3a126ac02e4097c04a175822194a
category: bugfix
bugzilla: https://gitee.com/openeuler/kernel/issues/I5IZ9C

Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id=93a1f0755edc3a126ac02e4097c04a175822194a



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

commit 12131008 upstream.

The G12A tohdmi has a custom put() operation which returns 0 when the value
of the mux changes, meaning that events are not generated for userspace.
Change to return 1 in this case, the function returns early in the case
where there is no change.
