phy: mdiobus_register(): initialize all phy_map entries
Herbert Valerio Riedel [Wed, 10 May 2006 16:12:57 +0000 (12:12 -0400)]
make sure phy_map entries whose PHY address is masked are initialized
to NULL, given that other code (such as mdiobus_unregister for
instance) assumes that non-NULL phy_map entries are allocated
phy_devices
