Subject: [PATCH 4/5] mtd: rawnand: davinci: Get rid of the legacy interface implementation
Date: Fri,  1 May 2020 12:07:28 +0200	[thread overview]
Message-ID: <20200501100729.1237040-5-boris.brezillon@collabora.com> (raw)
In-Reply-To: <20200501100729.1237040-1-boris.brezillon@collabora.com>

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