From 298cf9beb9679522de995e249eccbd82f7c51999 Mon Sep 17 00:00:00 2001 From: Lennert Buytenhek Date: Wed, 8 Oct 2008 16:29:57 -0700 Subject: [PATCH] phylib: move to dynamic allocation of struct mii_bus This patch introduces mdiobus_alloc() and mdiobus_free(), and makes all mdio bus drivers use these functions to allocate their struct mii_bus'es dynamically.
