Adam Ford c9e709dece serial: mctrl_gpio: Check for NULL pointer 
[ Upstream commit 37e3ab00e4 ]

When using mctrl_gpio_to_gpiod, it dereferences gpios into a single
requested GPIO.  This dereferencing can break if gpios is NULL,
so this patch adds a NULL check before dereferencing it.  If
gpios is NULL, this function will also return NULL.
