I am guessing this is tested by Michael against 3.3.y.
I am wondering about one detail about the patch (please forgive my
ignorance):

This part makes sense and seems similar to what is done for other
Atheros bluetooth adaptors that need firmware loaded at run time, like
the AR3011.

No other chip other than the AR3012 seems to add entries here. Could
you add a comment explaining why the AR5BBU22 is listed but not e.g.
the AR5BBU12?

Is the AR5BBU22 an AR3012?
Curious,
