I would apply bug-fix, cleanup, and refinement patches first and then apply v2 related patches.
So bug-fix, cleanup, and refinement patches could be backported to old version branch without any v2 related patches.
When I apply this patch, conflicts happen.
Please rebase this series onto mediatek-drm-next, and apply this patch before v2 related patches.

CK
