8561b10f6e [PATCH] USB: move the usb hcd code to use the new class code.
This moves a kref into the main hcd structure, which detaches it from
the class device structure.

Great!  FWIW I've briefly tested a modified version of usbatm using
the list head in struct urb instead of creating a wrapper struct, and I
haven't seen any failures yet.  So I tend to believe that your "should
be" actually means "is" :)

OK then how about the following (essentially documentation) patch?

27d72e8572 [PATCH] usb suspend updates (interface suspend)
This is the first of a few installments of PM API updates to match the
recent switch to "pm_message_t".  This installment primarily affects
USB device drivers (for USB interfaces), and it changes the handful of
drivers which currently implement suspend methods:

    - <linux/usb.h> and usbcore, signature change

    - Some drivers only changed the signature, net effect this just
      shuts up "sparse -Wbitwise":
	* hid-core
	* stir4200

    - Two network drivers did that, and also grew slightly more
      featureful suspend code ... they now properly shut down
      their activities.  (As should stir4200...)
	* pegasus
	* usbnet

Note that the Wake-On-Lan (WOL) support in pegasus doesn't yet work; looks
to me like it's missing a request to turn it on, vs just configuring it.
The ASIX code in usbnet also has WOL hooks that are ready to use; untested.

Initial git repository build. I'm not bothering with the full history,
even though we have it. We can create a separate "historical" git
archive of that later if we want to, and in the meantime it's about
3.2GB when imported into git - space that would just make the early
git days unnecessarily complicated, when we don't have a lot of good
infrastructure for it.

Let it rip!
