Subject: [PATCH] mtd: nand: mtk: deselect the chip that was selected in resume function
Date: Wed, 1 Nov 2017 14:19:57 +0800 [thread overview]
Message-ID: <1509517197-60350-1-git-send-email-xiaolei.li@mediatek.com> (raw)
From: Xiaolei Li <xiaolei.li@mediatek.com>
It is necessary to deselect the chip if it was selected before.
But now we only select chips when resume nand driver.
So, deselect the chip after doing nand reset.
