I think so, and overall I like the aproach and the implementation. Thanks!

Just got the stacktrace on [1] though when running kernel with this 
patchset. The trace popped during shutdown, and the machine froze 
completely; I didn't have any kind of external console connected, so 
unfortunately I don't have the beginning of the whole thing.

I haven't been able to reproduce it so far. This was after several 
"parallel" plug/remove cycles of multiple HID devices driven by multiple 
different drivers.

I haven't performed any analysis what this might be yet.
