Ah, sorry about that, our emails crossed paths.

As for the other patch (I mean 1/2), did you follow the instructions in
include/drm/README, specifically the section titled "When and how to
update these files" ?
Your commit message makes it look like you just applied that one change
instead of syncing with `make headers_install`.

Cheers,
