From 840b2f8dd2d0579e517140e1f9bbc482eaf4ed07 Mon Sep 17 00:00:00 2001 From: Miquel Raynal Date: Thu, 16 Dec 2021 12:16:39 +0100 Subject: [PATCH 02/15] mtd: nand: Add a new helper to retrieve the ECC context 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.
