Subject: [PATCH 3/3] mtd: rawnand: gpio: Get rid of the legacy interface implementation
Date: Wed,  3 Jun 2020 17:07:46 +0200	[thread overview]
Message-ID: <20200603150746.1423257-4-boris.brezillon@collabora.com> (raw)
In-Reply-To: <20200603150746.1423257-1-boris.brezillon@collabora.com>

Now that exec_op() is implemented, we can get rid of the legacy interface
implementation.
