Subject: [PATCH] Input: mousedev - fix /dev/input/mice minor number

The mousedev always used relative minor number 31 for MOUSEDEV_MIX
(/dev/input/mice), but alsolute minor number was 63. Commit
7f8d4cad1e4e11a45d02bd6e024cc2812963c38a ("Input: extend the number
of event (and other) devices") changed it to 31 alsolute minor number.
