Logging messages sometimes had duplicated "ATL1E" output. For instance: ATL1E 0000:03:00.0: ATL1E: eth0 NIC Link is Up<100 Mbps Full Duplex> is now: ATL1E 0000:03:00.0: eth0: NIC Link is Up <100 Mbps Full Duplex> Add some consistency to logging messages Add some missing \n's to logging messages Miscellaneous typo spelling corrections Change atl1e_validate_option argument from pdev to adapter Signed-off-by: Joe Perches <joe@perches.com> Signed-off-by: David S. Miller <davem@davemloft.net>
