I've tested the last patch and it seems to work as required. I did a series
of generic<->specific driver rebindings both ways in a loop and it works.

Thanks Henrik!

I'm not sure, though, if one thing works as it should: the quirks are not
reset when changing the driver. So, quirks set by one driver may affect
behavior of another. I don't understand full quirks usage and ownership yet,
so can't argue if this is right or wrong.

Regarding the code, could it be the time to fix naming of report
descriptor-handling functions to improve distinction from report-handling
ones? I'm attaching a patch applying on top of Henrik's changes which should
illustrate the proposal.

Thanks!

Sincerely,
Nick
