These are both upstream cherry-picks, representing a wholy new and
separate driver.  It appears to autoload appropriatly so ought to have
very low regression potential outside of the HP product line.

I would say that the bug shows only testing of this against a mainline
kernel, there is not any documentation for testing of these specific
cherry-picks back to saucy or trusty, has this actually been tested at
all against our kernels?  If this has been tested somewhere, could you
document that in the bug.

With testing documentation in place:
