3.16.45-rc1 review patch. If anyone has any objections, please let me know.
------------------
From: Seung-Woo Kim <sw0312.kim@xxxxxxxxxxx>
commit 60a2362f769cf549dc466134efe71c8bf9fbaaba upstream.
After freeing pin from regulator_ena_gpio_free, loop can access
the pin. So this patch fixes not to access pin after freeing.
