Subject: [PATCH 2/3] psmouse: add psmouse_queue_work() for ps/2 extension to
 make use of


psmouse_queue_work is passed a delayed_work struct, and queues up the work
with kpsmouse_wq.  Since we're dealing with delayed_work stuff, this
also switches resync_work to a delayed_work struct as well, and makes
use of psmouse_queue_work when doing a resync within psmouse-base.

Dmitry, is this what you had in mind?
