Hello Jason-JH,

you must've missed my commit, sent two days ago, which is doing the same:

https://lore.kernel.org/lkml/20220620102454.131417-1-angelogioacchino.delregno@xxxxxxxxxxxxx/T/#u

Anyway, I have avoided to rename the definition, as from what I understand
MT8365 has only one dither mod and that's called "DITHER", not "DITHER0"...
...but I've added the suffix to the array assignment, as that's what we have
in the enumeration.

I think that #define MT8365_MUTEX_MOD_DISP_DITHER should be kept as-is.

Also... this commit is not fixing anything, as it was already working before,
so the Fixes tag shouldn't be present.

Regards,
Angelo
