3.0-stable review patch. If anyone has any objections, please let us know.
------------------ From: David Engraf <david.eng...@sysgo.com> 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.
