Hi Rosen,
Patrick Havelange is stepping down from maintenance of this driver, so
ftm-quaddec is currently considered to be in an Orphan status.[^1] If a
new maintainer comes along in the future to maintain this driver, they
will be able to assist the review of this patch.
Sincerely,
William Breathitt Gray
