Some more info after some staring:
We could've made the lock_class_key only static storage so that lockdep
is happy but then struct bus_type embeds the *whole* lock_class_key and
not a pointer to it.
Which leaves us with either:
* this fix postponing the problem
* or Greg coming and saying, you're using bus_type all wrong and you
shouldn't and you should remove it completely! :-)
Which would be much better.
Thx.
