[PATCH 0/3] serial: Don't check for mctrl_gpio_to_gpiod() returning error

[Geert Uytterhoeven <geert+renesas@glider.be>]

	Hi Greg, Jiri,

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 in serial drivers if
mctrl_gpio_to_gpiod() returns an error value.  A simple NULL check is
sufficient.

This series follows the spirit of commit 445df7ff3fd1a0a9 ("serial:
mctrl-gpio: drop usages of IS_ERR_OR_NULL") in the mctrl-gpio core.

Thanks!
