Subject[PATCH] mmc: sdhci-of-at91: fix pm runtime unbalanced issue in error path
Date
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.
