[Intel-wired-lan] [PATCH 04/10] igc: Use netdev log helpers in igc_dump.c
Andre Guedes

Wed Mar 25 00:38:18 UTC 2020
In igc_dump.c we print log messages using dev_* and pr_* helpers,
generating inconsistent output with the rest of the driver. Since this
is a network device driver, we should preferably use netdev_* helpers
because they append the interface name to the message, helping making
sense out of the logs.
This patch converts all dev_* and pr_* calls to netdev_*. It also takes
this opportunity to remove the '\n' character at the end of messages
since is it automatically added by netdev_* log helpers.
Quick note about igc_rings_dump(): This function is always called with
valid adapter->netdev so there is not need to check it.
