This patch series fixes a couple of issues with the unbinding of the PHY
drivers and then bringing down a network interface. The first is a NULL
pointer de-reference and the second was an incorrect warning being
triggered.

When phy_is_started() was added to catch incorrect PHY states,
phy_stop() would not be qualified against PHY_DOWN. It is possible to
reach that state when the PHY driver has been unbound and the network
device is then brought down.
Fixes: 2b3e88ea6528 ("net: phy: improve phy state checking")
Signe
If we have unbound the PHY driver prior to calling phy_detach() (often
via phy_disconnect()) then we can cause a NULL pointer de-reference
accessing the driver owner member. The steps to reproduce are:

In rx_request_irq(), it will just return what irq_set_affinity_hint()

If successful, __ibmvnic_open and reset_sub_crq_queues,
if no device queues exist, will return an uninitialized

The following features are supported:
- VLAN-aware bridge offloading
- VLAN-unaware bridge offloading
- FDB offloading (learning, ageing)
- Switchport configuration
Currently there are some limitations like:
- Only 1 VLAN-aware bridge instance supported
- FDB ageing timeo

This driver is a virtual driver stacked on top of Ethernet interfaces.
When this driver transmits data on the Ethernet device, the skb->protocol
setting is inconsistent with the Ethernet header prepended to the skb.
This causes a user listening on the Ethernet interface with an AF_PACKET

drives its MDIO interface among other things, the driver now requests
and manage that clock during .probe() and .remove() accordingly.
