Hi, in addition to what Russell said, please remove the extra newline
between function call and return value check, i.e. instead of
  ret = phy_xyz(...);

  if (ret)
     return ret;

  ret = phy_xyz(...);

  if (ret)
     return ret;

do
  ret = phy_xyz(...);
  if (ret)
     return ret;

  ret = phy_xyz(...);
  if (ret)
     return ret;

This is how this driver does this everywhere else.

Do you have a device that uses this WoL feature?
