From 17b9724cf84aa32f15334c23d5df34ad3cb885f3 Mon Sep 17 00:00:00 2001 From: Boris BREZILLON Date: Mon, 16 Nov 2015 14:37:35 +0100 Subject: [PATCH 52/81] mtd: nand: add an mtd_to_nand() helper Some drivers are retrieving the nand_chip pointer using the container_of macro on a struct wrapping both the nand_chip and the mtd_info struct while the standard way of retrieving this pointer is through mtd->priv. Provide an helper to do that.
