[PATCH v2 3/3] serial: 8250: Remove check for specific mctrl_gpio_init() return value

From: Schrempf Frieder
Date: Thu Aug 01 2019 - 14:45:38 EST


From: Frieder Schrempf <frieder.schrempf@xxxxxxxxxx>

Now that the mctrl_gpio code returns NULL instead of ERR_PTR(-ENOSYS)
in cases when CONFIG_GPIOLIB is disabled, we can safely remove this
check.
