From 17cb4b8f327eb983cef7c510fcf77f1635a00e48 Mon Sep 17 00:00:00 2001 From: Scott Wood Date: Mon, 30 May 2016 13:57:56 -0500 Subject: mtd: nand: Add+use mtd_to/from_nand and nand_get/set_controller_data These functions are part of the Linux 4.6 sync. They are being added before the main sync patch in order to make it easier to address the issue across all NAND drivers (many/most of which do not closely track their Linux counterparts) separately from other merge issues.
