From: Greg Kroah-Hartman
Date: Thu Oct 03 2013 - 00:12:10 EST


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

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

From: Alexander Usyskin <alexander.usyskin@xxxxxxxxx>

commit 4a704575cc1afb3b848f096778fa9b8d7b3d5813 upstream.

Unset init_clients_timer and amthif_stall_timers
in mei_reset in order to cancel timer ticking and hence
avoid recursive reset calls.
