4.14-stable review patch. If anyone has any objections, please let me know. ------------------ From: Christian Lamparter <chunkeey@xxxxxxxxx> commit 1eec7151ae0e134bd42e3f128066b2ff8da21393 upstream. This belated patch implements Andrew Lunn's request of "remove the phy_read() and phy_write() functions." <https://lore.kernel.org/patchwork/comment/902734/> While seemingly harmless, this causes the switch's user port PHYs to get registered twice. This is because the DSA subsystem will create a slave mdio-bus not knowing that the qca8k_phy_(read|write) accessors operate on the external mdio-bus. So the same "bus" gets effectively duplicated.
