Subject: [PATCH] Fix PHY Lib support for gianfar and ucc_geth
Date: Tue, 5 Feb 2008 16:35:30 -0600 [thread overview]
Message-ID: <12022509302322-git-send-email-afleming@freescale.com> (raw)
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.
