Subject: [PATCH 02/15] mtd: nand: Add an helper returning the number of eraseblocks per target
Date: Thu, 21 Feb 2019 10:15:14 +0100	[thread overview]
Message-ID: <20190221091527.20497-3-miquel.raynal@bootlin.com> (raw)
In-Reply-To: <20190221091527.20497-1-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.
