Hi David, Rob,
I will address all of Rob's comments below.
Since a part of the patch was applied to 'net-next', would you like me to
send a new patch (based on the applied one), or a 'V2' of this patch ?
Thanks

If the ibmvnic driver is not in the VNIC_OPEN state, return from

The lan911x family of devices require supplying from 3.3 V power
supplies (connected to VDD_IO, VDD_A and VREG_3.3 pins). The existing
driver however obtains only VDD_IO and VDD_A regulators in an optional
way so document this in bindings.
