The fix for the regression has landed in the mainline tree, so you can
now backport

443290d70b01e9c35830c300e3247c06581b594c
drm/amd/display: Add AV mute wait frames to dce110_set_avmute

and

3141e3d61469bba2624a91c5e2407f110b33b29e
drm/amd/display: Check for tg ops in dce110_set_avmute

to the stable kernels (7.1, 6.18 and 6.12), both have 'Cc: stable'. Note
that the 'Fixes' tag in the second commit refers to a commit on the
drm-next branch and not the corresponding commit from the drm-fixes
branch, which might be confusing.

Thanks,
Viktor
