Subject: [PATCH v2 00/12] gpio: use new GPIO line value setter callbacks

Commit 98ce1eb1fd87e ("gpiolib: introduce gpio_chip setters that return
values") added new line setter callbacks to struct gpio_chip. They allow
to indicate failures to callers. We're in the process of converting all
GPIO controllers to using them before removing the old ones. This series
converts another round of GPIO drivers.

Changes in v2:
- fix a NULL-pointer dereference in gpio-reg: use the correct function
  pointer when calling the setter callback directly
- Link to v1: https://lore.kernel.org/r/20250617-gpiochip-set-rv-gpio-v1-0-903703881fa2@linaro.org
