Subject: Re: [PATCH] drm/i915: Replace *_reference/unreference() or

Since this is done with cocci it's good to reference or include the cocci
patch you've used in the commit message.

When submitting a driver patch, please make sure you also include driver
maintainers and driver-specific mailing lists, not just dri-devel.
scripts/get_maintainers.pl should help you with figuring these out.
Thanks, Daniel
