A style issue: better write a nice sentence than these tags. For the
patch at hand, I'd preferred something like: "Only add an id for
supporting AST2600. No functional changes are required."
I assume that there areno further changes required for AST2600.

I'll add the patch to drm-misc-next. Thanks!
Best regards
