From 75fee59550a9899fd9438ebc0a64c972829a8dd2 Mon Sep 17 00:00:00 2001 From: Joachim Eastwood Date: Wed, 29 Jul 2015 00:09:03 +0200 Subject: stmmac: remove setup/free glue callbacks As all dwmac-* drivers have been converted to have a proper probe function the setup callback can now be removed. Also remove the free callback that wasn't used by any driver. New dwmac-* drivers should implement standard probe and remove functions to preform any needed setup and teardown.
