Subject: [PATCH v4 05/13] mmc: sdhci-of-arasan: fix clk issue in sdhci_arasan_remove()
Date: Tue, 26 Jan 2016 18:15:45 +0800	[thread overview]
Message-ID: <1453803353-6266-6-git-send-email-jszhang@marvell.com> (raw)
In-Reply-To: <1453803353-6266-1-git-send-email-jszhang@marvell.com>

sdhci_pltfm_unregister() could operate host's registers, it will cause
problems if the clk is already disabled and unprepared. Fix this issue
by moving the clk_disable_unprepare() call to the end of remove
function.
