[PATCH v4 3/5] net: stmmac: remove some __func__ printing
From: LABBE Corentin
Date: Thu Nov 05 2015 - 08:15:45 EST
Now that stmmac use netdev_xxx, some __func__ are not necessary since their
use was to clearly identify which driver was logging.
Moreover, as pointed by Joe Perches, using __func__ in xxx_dbg functions
is relatively low value and dynamic debug can add it.
This patch remove __func__ where such printing is useless.
