Hi,

this should add runtime power management to the powermate driver.
In order to do so the driver had to be changed to provide open & close
methods. Please test.

I was workinf on adding suspend and resume hooks to input devices to
reset them into sane state automatically. I am wondering if I should
call driver's suspend and resume only for open input devices and

If you do that open() would have to redo all initialisation work probe()
would do.

provide mutual exclusion with open and close. DO you think it will
help with reagrd to adding autopm support to USB devices?

Mutual exclusion is a very good idea. And telling input devices that
they are open is also a good idea. But this will be difficult, as open()
will almost certainly wish to do as memory allocations can trigger
an autoresume.
