From 5c32bac98c705ce409ac26b5120c14ece8bd9209 Mon Sep 17 00:00:00 2001 From: Andre Guedes Date: Tue, 24 Mar 2020 17:38:18 -0700 Subject: [PATCH] igc: Use netdev log helpers in igc_dump.c 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_*. Quick note about igc_rings_dump(): This function is always called with valid adapter->netdev so there is not need to check it.
