From: Yegor Yefremov <yegorslists@xxxxxxxxxxxxxx> This is another attempt to integrate mctrl_gpio helpers into 8250 driver. Previous attempt failed because devm_gpiod_get_index_optional() broke some x86 devices via redefining RX ping to GPIO. See [1] for details. "serial: mctrl_gpio: restrict MCTRL initialization" patch uses device_property_present() routine to check, if mctrl related property is available for device and only then a corresponding structure will be initialized.
