From f883199d17b87e86a4ebd50bdee69285814bdce7 Mon Sep 17 00:00:00 2001 From: Xiaolei Li Date: Thu, 2 Nov 2017 10:05:07 +0800 Subject: mtd: nand: mtk: use nand_reset() to reset NAND devices in resume function Previously, we only select chips and then send reset command to a NAND device during resuming nand driver. There is a lack of deselecting chips. It is advised to reset and initialize a NAND device using nand_reset().
