Adam Ford 62f353a1bf 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.
