From 15cf6dde99e40bf571a5ca48376650e163fcd30f Mon Sep 17 00:00:00 2001 From: Andy Fleming Date: Tue, 5 Feb 2008 16:35:30 -0600 Subject: Fix PHY Lib support for gianfar and ucc_geth The PHY Lib now uses mutexes instead of spin_locks. ucc_geth and gianfar both grab the locks in their mdio_reset functions, so they need to use mutex_(un)lock instead. This was not caught until someone tested it on an SMP system.
