the -mh patches contain a specific version for the hidp driver with
report protocol support that is not mainline. It will also never get
into mainline, because the solution is the generic HID driver.

I think the force for that have to be driven by me. We all agreed on how
this should be done, but there are some things pending that I like to
see merged first mainline (subclass support and sysfs integration)
before I look at it again. Check the mailing list archive for comments
about that.
