[PATCH 1/4] MIPS: rb532: gpio: use new line value setter callbacks

From: Bartosz Golaszewski
Date: Mon Apr 07 2025 - 03:36:13 EST


From: Bartosz Golaszewski <bartosz.golaszewski@xxxxxxxxxx>

struct gpio_chip now has callbacks for setting line values that return
an integer, allowing to indicate failures. Convert the driver to using
them.
