From 2df9d58fcc0f20d812f390e0b97df69d70d3152f Mon Sep 17 00:00:00 2001 From: Jisheng Zhang Date: Tue, 2 Feb 2016 19:55:06 +0800 Subject: [PATCH] mmc: sdhci-of-at91: fix pm runtime unbalanced issue in error path 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.
