net: phy: fix memory leak in device-create error path
A recent commit introduced a late error path in phy_device_create() which fails to release the device name allocated by dev_set_name(). Fixes: 13d0ab6750b2 ("net: phy: check return code when requesting PHY driver module") Cc: Heiner Kallweit <hkallweit1@gmail.com> Signed-off-by: Johan Hovold <johan@kernel.org> Signed-off-by: David S.
