mmc: sdhci-of-at91: fix pm runtime unbalanced issue in error path

Jisheng Zhang · storulf · commit 2df9d58fcc0f · 2016-02-02T14:09:14.000+01:00
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.
