If there's no special ordering requirement for mdiobus_unregister(), then driver code can be simplified by using a device-managed version of mdiobus_register(). Prerequisite is that bus allocation has been done device-managed too. Else mdiobus_free() may be called whilst bus is still registered, resulting in a BUG_ON(). Therefore let devm_mdiobus_register() return -EPERM if bus was allocated non-managed. Signed-off-by:
