Re: [PATCH v3] drm/fourcc: Add AXBXGXRX106106106106 format

[Matteo Franchin <matteo.franchin@arm.com>]

v3 includes the Signed-off-by and Acked-by lines in the commit. No
other changes.

At this point, I'd need some help from a maintainer/committer to merge
this, I understand.

Daniel Vetter, are you happy to do this or does this work differently?

Many thanks,
Matteo
