-Subject: net: stmmac: fix notifier registration
-
-We cannot register the same netdev notifier multiple times when probing
-stmmac devices. Register the notifier only once in module init, and also
-make debugfs creation/deletion safe against simultaneous notifier call.
-
-Fixes: 481a7d154cbb ("stmmac: debugfs entry name is not be changed when udev rename device name.")
