Please make use of dev_err(phy->dev, so we know which PHY has
configuration problems.

You still have not Cc'd me on your patches. Please can you either:

1) use get_maintainer.pl to find out whom you should be sending
your patches to
or
2) include me in your cc for this patch set as phylink maintainer in
your patch set so I can review your use of phylink.

Consider your patches NAK'd until you send them to me so that I can
review them.

Thanks.

Hi Russell,

I will CC you on the next version of this series. In reality I was
just asked by Vladimir Oltean to crosspost to netdev. This is a
series for the Generic PHY subsystem.
Sorry about the confusion.
