Subject: [PATCH 3.2 090/110] NET: AX.25: Stop heartbeat timer on disconnect.

3.2.71-rc1 review patch.  If anyone has any objections, please let me know.

------------------

From: Richard Stearn <richard@...-stearn.demon.co.uk>

commit da278622bf04f8ddb14519a2b8214e108ef26101 upstream.

This may result in a kernel panic.  The bug has always existed but
somehow we've run out of luck now and it bites.
