[PATCH 02/27] mtd: nand: add an mtd_to_nand() helper

From: Boris Brezillon
Date: Mon Nov 16 2015 - 08:49:25 EST

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.
