Subject: [PATCH v2 0/5] net: 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 all GPIO chips implemented under drivers/net/.

Changes in v2:
- propagate the return value of mcp251x_spi_write() in the mcp251x
  driver up to the new GPIO callbacks (and the old request() too)
- check the return value of phy_read_mmd() as well in qca807x
- Link to v1: https://lore.kernel.org/r/20250610-gpiochip-set-rv-net-v1-0-35668dd1c76f@linaro.org
