After mmsys and drm change DITHER enum to DDP_COMPONENT_DITHER0,
mmsys header can remove the useless DDP_COMPONENT_DITHER enum.

Chun-Kuang, I think it would make sense to take that through your tree as it
depends on the previous patches.

I provide you a stable tag so that you can take it:
v5.18-next-vdso0-stable-tag

After I take this tag, I find one checkpatch warning:

WARNING: DT compatible string "mediatek,mt8195-mmsys" appears
un-documented -- check ./Documentation/devicetree/bindings/
#670: FILE: drivers/soc/mediatek/mtk-mmsys.c:390:
+               .compatible = "mediatek,mt8195-mmsys",

I think this tag lost one binding patch, it's better that this tag has
no this warning.


Sorry for the late reply I was sick.
The warning is, because the stable branch misses commit:
https://git.kernel.org/pub/scm/linux/kernel/git/matthias.bgg/linux.git/commit/?h=v5.18-next/soc&id=81c5a41d10b968ea89d5f44fe1e5c2fc70289209

So it's not a real issue and will go away once our branches land in upstream.
Is it OK for you to ignore the issue?

It's OK for me, but the patch would go through different maintainer's
tree and I'm not sure it's OK for all of them. So I would wait for the
necessary patch land in upstream.


Ok makes sense. Sorry for the bad coordination from my side on this.

Matthias
