Subject: regulator: core: Fix regualtor_ena_gpio_free not to access pin after freeing
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.
