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.

Hi Henrik,

thanks a lot for looking into this. I will look into the patches in more
detail tomorrow. I am now just adding Nikolai to CC, as he was the first
one to bring this up and actually has a driver that exposed the fact that
just freeing/reinstatiating rdesc is not enough.

Thanks Henrik, Jiri!

I'll be testing this as soon as I can.

Sincerely,
Nick
