From db0dbae9d9680bce69fe1ce775709e60c8ee9c29 Mon Sep 17 00:00:00 2001 From: Wade Farnsworth Date: Wed, 20 Jun 2007 10:15:10 +1000 Subject: [PATCH] [POWERPC] Add a check for keyboard/mouse device nodes in check_legacy_ioport() The device tree for the MPC8641 HPCN does not implement the device type property for I8042 nodes. In addition to checking the I8042 node's device type, also match the keyboard and/or mouse nodes' compatible property.
