This patchset contains a resolution to the problem with
driver-specific modification of the report descriptor. The core of the
problem lies with the dual semantics of hid_parse_report(), which is
therefore split into two functions. As a consequence, the hid core can
handle the rebind case internally, with no changes to the
drivers. Out-of-tree drivers will work fine as long as they operate in
the same way as the in-kernel drivers.

The first two patches are bug fixes found in the process. I am hoping
for some test feedback on those. The third patch is the main one.

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
