From 17b9724cf84aa32f15334c23d5df34ad3cb885f3 Mon Sep 17 00:00:00 2001
From: Boris BREZILLON <boris.brezillon@free-electrons.com>

Subject: [PATCH 52/78] 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.
