I didn't give you an explicit R-b, but that's fine, you can keep
it as I think the patch is fine.

Do you see the indentation is off here? :-)
Please, run checkpatch.pl before sending the patch, as well.
Besides, what patch is this? Are you replacing kmemdup_array with

on a clean drm-tip repository.
