Subject: net: dsa: mv88e6xxx: drop adjust_link to enabled phylink
X-Git-Tag: microblaze-v5.4-rc1~109^2~22
X-Git-Url: http://git.monstr.eu/?a=commitdiff_plain;h=7fb5a711545d7d25fe9726a9ad277474dd83bd06;p=linux-2.6-microblaze.git

net: dsa: mv88e6xxx: drop adjust_link to enabled phylink

We have to drop the adjust_link callback in order to finally migrate to
phylink.

Otherwise we get the following warning during startup:
  "mv88e6xxx 2188000.ethernet-1:10: Using legacy PHYLIB callbacks. Please
   migrate to PHYLINK!"

The warning is generated in the function dsa_port_link_register_of in
dsa/port.c:

  int dsa_port_link_register_of(struct dsa_port *dp)
  {
  	struct dsa_switch *ds = dp->ds;

  	if (!ds->ops->adjust_link)
  		return dsa_port_phylink_register(dp);

  	dev_warn(ds->dev,
  		 "Using legacy PHYLIB callbacks. Please migrate to PHYLINK!\n");
  	[...]
  }
