Can you please include at least one user of this call back in your patch
series?

Could you please keep the kernel doc entry up to date? I know we donot
have entries for all structs, but I am working in improving this.

Thanks for the comments on this series. I'll address them in the next
round. The user for this callback is not yet ready to be posted. I'll
try and move this patch to the end of the series so that the series can
be applied without this one.
Thanks
Sascha

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()
http://article.gmane.org/gmane.linux.power-management.general/58685

Sure, I'll add you to Cc next round. I'm halfway through updating this
series according to the comments I received, but got distracted. I hope
to send an update next week.
