The NL_SET_ERR_MSG_MOD function already adds the \n at the end.

Side question: do you think the ds->configure_vlan_while_not_filtering = false
from ksz9477.c and ksz8795.c serve any purpose, considering that you did
not need this setting for lan937x? If not, could you please send a patch
to remove that setting from those 2 other KSZ drivers? Thanks.
