[PATCH 3.10 14/55] mei: start disconnect request timer consistently

From: Greg Kroah-Hartman
Date: Wed Sep 03 2014 - 19:52:05 EST

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


From: Alexander Usyskin <alexander.usyskin@xxxxxxxxx>

commit 22b987a325701223f9a37db700c6eb20b9924c6f upstream.

Link must be reset in case the fw doesn't
respond to client disconnect request.
We did charge the timer only in irq path
from mei_cl_irq_close and not in mei_cl_disconnect
