Subject: [PATCH v2 02/15] mtd: nand: Add a helper returning the number of eraseblocks per target
Date: Mon, 4 Mar 2019 21:15:09 +0100 [thread overview]
Message-ID: <20190304201522.11323-3-miquel.raynal@bootlin.com> (raw)
In-Reply-To: <20190304201522.11323-1-miquel.raynal@bootlin.com>
From: Boris Brezillon <bbrezillon@kernel.org>
Some drivers in the raw NAND framework seems to need this helper, so
let's just add it instead of open-coding the logic.
