Message-Id: <20221005120501.3527435-2-clabbe@baylibre.com>

Subject: [PATCH 2/4] net: ethernet: xscale: fix printk issues
Fix all checkpatch issues about printk and co.
Some pr_xx are replaced by netdev_xxx when appropriate.
Furthermore, there are lot of typo on netdev_debug instead of
netdev_dbg; since this is ifdef-ed debug code, no need for a fixes tag.
