Subject: [PULL 11/26] m25p80: Introduce an helper to retrieve the BlockBackend of a device
Date: Fri, 1 Sep 2023 11:41:59 +0200 [thread overview]
Message-ID: <20230901094214.296918-12-clg@kaod.org> (raw)
In-Reply-To: <20230901094214.296918-1-clg@kaod.org>
It will help in getting rid of some drive_get(IF_MTD) calls by
retrieving the BlockBackend directly from the m25p80 device.
