But there is one more which applies here.\n\nIf the DSA master itself is on a bus that calls ->remove from ->shutdown\n(like dpaa2-eth, which is on the fsl-mc bus), there is a device link\nbetween the switch and the DSA master, and device_links_unbind_consumers()\nwill unbind the ar9331 switch driver on shutdown.\n\nSo the same treatment must be applied to all DSA switch drivers, which\nis: either use devres for both the mdiobus allocation and registration,\nor don't use devres at all.\n\nThe ar9331 driver doesn't have a complex code structure for mdiobus\nremoval, so just replace of_mdiobus_register with the devres variant in\norder to be all-devres and ensure that we don't free a still-registered\nbus."
