Subject: [PATCH 2/3] gpio: dwapb: drop ->irq_{request,release}_resources hooks
Date:   Fri,  8 Feb 2019 12:52:00 +0100
Message-Id: <20190208115201.7518-3-thomas.petazzoni@bootlin.com>

Those hooks implement the exact same behavior as the default hooks by
gpiolib, so there is no point in having a duplicated definition in
gpio-dwapb.
