[PATCH 3/3] net: mdio: rename mdio_device reset to reset_gpio

[David Bauer]

This renames the GPIO reset of mdio devices from 'reset' to
'reset_gpio' to better differentiate between GPIO and
reset-controller driven reset line.

Hi David

The mdiobus_register_gpiod() function also has a call to
mdio_device_reset(). So we end up resetting the GPIO twice.

It is probably better to pull this out of here, and
mdiobus_register_gpiod(), and do it once in mdiobus_register_device().
