oxnas: backport upstream NAND driver Signed-off-by: Daniel Golle <daniel@makrotopia.org>
2016-09-23 23:14:53 +00:00
From d45bc58dd3bdcaabc1d7d8d9b0b8dee826635cc6 Mon Sep 17 00:00:00 2001
From: Marc Gonzalez <marc_gonzalez@sigmadesigns.com>
Date: Wed, 27 Jul 2016 11:23:52 +0200
Subject: [PATCH] mtd: nand: import nand_hw_control_init()
The code to initialize a struct nand_hw_control is duplicated across
several drivers. Factorize it using an inline function.
