From b976168757f7f4adf05215884e8557aaa9f6792c Mon Sep 17 00:00:00 2001 From: Boris Brezillon Date: Thu, 6 Sep 2018 14:05:20 +0200 Subject: [PATCH] mtd: rawnand: Pass a nand_chip object to ecc->read_xxx() hooks Let's make the raw NAND API consistent by patching all helpers and hooks to take a nand_chip object instead of an mtd_info one or remove the mtd_info object when both are passed. Let's tackle all ecc->read_xxx() hooks at once.
