This should be fixed by:
commit f74eef95e33a07379aa2b950c7f313cbfd55ebbe Author: Hitoshi Mitake <mitake@dcl.info.waseda.ac.jp> Date: Wed Oct 13 11:35:40 2010 -0700
Input: mousedev - correct lockdep annotation
When annotating mutex to avoid false lockdep reports we should not be using MOUSEDEV_MIX as lock subclass but rather SINGLE_DEPTH_NESTING.
Signed-off-by: Hitoshi Mitake <mitake@dcl.info.waseda.ac.jp> Signed-off-by: Dmitry Torokhov <dtor@mail.ru>
once Linus pulls from my tree.
Thanks.
