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 all GPIO chips implemented under drivers/usb/serial/.

Changes in v2:
- reduce the number of changes in patch 2/2 by simply changing the
  function prototype and returning a value without reshuffling the
  implementation (Johan)
- Link to v1: https://lore.kernel.org/r/20250610-gpiochip-set-rv-usb-serial-v1-0-a9343ca109e8@linaro.org
