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

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

From: David Engraf <[email protected]>

commit bea1906620ce72b63f83735c4cc2642b25ec54ae upstream.

Fix the usage of mod_timer() and make the driver usable. mod_timer() must
be called with an absolute timeout in jiffies. The old implementation
used a relative timeout thus the hardware watchdog was never triggered.
