From 5b9215acb5182355a8a3c9f0a930e6b51c6eea57 Mon Sep 17 00:00:00 2001 From: Miquel Raynal Date: Wed, 27 Jan 2021 21:30:17 +0100 Subject: mtd: rawnand: Try not to use the ECC private structures Most of the time, there is no need to use the software ECC Hamming and BCH algorithms private context to know their configuration. All the data has been stored by their ->init_ctx() hook in the generic NAND ECC engine structure, so use this one when possible.
