From mboxrd@z Thu Jan 1 00:00:00 1970 From: jszhang@marvell.com (Jisheng Zhang) Date: Tue, 26 Jan 2016 18:42:34 +0800 Subject: [PATCH] mmc: sdhci-of-at91: fix pm runtime unbalanced issue in error path Message-ID: <1453804954-3490-1-git-send-email-jszhang@marvell.com> To: linux-arm-kernel@lists.infradead.org List-Id: linux-arm-kernel.lists.infradead.org The device power usage counter is increased by pm_runtime_get_noresume but isn't decreased in err_add_host error path. Fix this issue by calling pm_runtime_put_noidle() in the error path to restore the device's power usage counter.
