[PATCH 06/23] Input: mousedev - fix memory leak

[Chris Wright <chrisw@sous-sol.org>]

-stable review patch.  If anyone has any objections, please let us know.
------------------

Apparently, "while true; do cat </dev/null >/dev/input/mice; done" causes
an OOM in a short amount of time. Funny that nobody noticed, it actually
is very easy to trigger just by switching between VT1 and VT7...
