Subject: [PATCH 02/22] mtd: rawnand: arasan: Check the proposed data interface is supported
Date: Wed, 5 May 2021 23:37:30 +0200 [thread overview]
Message-ID: <20210505213750.257417-3-miquel.raynal@bootlin.com> (raw)
In-Reply-To: <20210505213750.257417-1-miquel.raynal@bootlin.com>
Check the data interface is supported in ->setup_interface() before
acknowledging the timings.
