it looks like you might be missing some important people in your recipient list.
get_maintainer.pl shows me:
- Archit Taneja <arch...@codeaurora.org> (maintainer:DRM DRIVERS FOR BRIDGE
CHIPS)
- Andrzej Hajda <a.ha...@samsung.com> (maintainer:DRM DRIVERS FOR BRIDGE CHIPS)
- dri-de...@lists.freedesktop.org (open list:DRM DRIVERS)
So these should definitly be included in your recipients, as they're the
ones that will apply your patch :-)
One further nit below.

braces around the single dev_err are not necessary.
