So the one mentioned in the rt-rk article and a load of CVEs is _not_
QCA8084 but is APQ8084. Sounds like a lot of people are getting stuff
wrong - which is hardly surprising as there are people that seem to
_enjoy_ getting the technical details wrong. I haven't worked out if
it's intentional malace, or they're just fundamentally lazy individuals
who just like to screw with other people.

Sigh.
