Please use scripts/get_maintainer.pl on the patch to figure out who it
should be sent to. This file is not maintained by us, so we can't just
merge it.

For example:

$ scripts/get_maintainer.pl 0001-drm-add-picture-aspect-ratio-flags.patch 
David Airlie <airlied at linux.ie> (maintainer:DRM DRIVERS)
dri-devel at lists.freedesktop.org (open list:DRM DRIVERS)
linux-kernel at vger.kernel.org (open list)

Of course, since you ultimately aim for a change in drm/i915, you should
also Cc: intel-gfx.

BR,
Jani.
