I'm actually interested in this patch, as I am developing a thermal
sensor driver that has hardware-assisted temperature-trip interrupts.
I'm testing out your patches now, and will probably end up using them on
my local tree. With help of this (and a few other changes I need to
make), my driver should be ready to post soon.

So, I'll try to post my driver soon as an example, if you'd like. I'd
also appreciate a CC on any future revisions, if you don't mind. I'm
subscribed to the list, but it's not always easy to pick out the signal
from the noise.

Thanks,
Brian

P.S. Time for a mild complaint: I think it seems to be a bit of a plague
in the thermal subsystem; there are API's, and even user-space ABI's
(!!) that have no in-kernel users! e.g., generate_netlink_event()
