+Subject: [PATCH] net: dsa: b53: Use dev_{err,info} instead of pr_*
+
+This change allows us to see which device the err or info messages are
+referring to if we have multiple b53 compatible devices on a board.
+
+As this removes the only pr_*() calls in this file we can drop the
+definition of pr_fmt().
