Subject: [PATCH net-next v2 1/7] net: dsa: mv888e6xxx: do not use netdev printing
The mv888e6xxx driver accesses a port's netdev mostly for printing.
This is bad for 2 reasons: DSA and CPU ports do not have a netdev
pointer; it doesn't give us a correct picture of why a DSA driver might
need to access a port's netdev.
Instead simply use dev_* printing functions with chip->dev (or ds->dev
depending on the scope, both guaranteed to exist), with a p%d prefix for
the target port.
