Subject: [PATCH v6 13/28] mtd: nand: Add a new helper to retrieve the ECC context
Date: Thu, 16 Dec 2021 12:16:39 +0100	[thread overview]
Message-ID: <20211216111654.238086-14-miquel.raynal@bootlin.com> (raw)
In-Reply-To: <20211216111654.238086-1-miquel.raynal@bootlin.com>

Introduce nand_to_ecc_ctx() which will allow to easily jump to the
private pointer of an ECC context given a NAND device. This is very
handy, from the prepare or finish ECC hook, to get the internal context
out of the NAND device object.
