Since commit 1d267ea6539f2663 ("serial: mctrl-gpio: simplify init routine"), mctrl_gpio_init() returns failure if the assignment to any member of the gpio array results in an error pointer. Since commit c359522194593815 ("serial: mctrl_gpio: Avoid probe failures in case of missing gpiolib"), mctrl_gpio_to_gpiod() returns NULL in the !CONFIG_GPIOLIB case. Hence there is no longer a need to check for mctrl_gpio_to_gpiod() returning an error value. A simple NULL check is sufficient. This follows the spirit of commit 445df7ff3fd1a0a9 ("serial: mctrl-gpio: drop usages of IS_ERR_OR_NULL") in the mctrl-gpio core.
