serial: mctrl_gpio: Check for NULL pointer
[ Upstream commit 37e3ab00e4734acc15d96b2926aab55c894f4d9c ]
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.
