Subject: [PATCH v1 0/2] HID: Fix regression resulting from commit 532223c8ac57

Jiri, Bastien,

This series of 2 patches fixes a regression introduced by commit 532223c8ac57
("HID: logitech-hidpp: Enable HID++ for all the Logitech Bluetooth devices")
that caused my Logitech Bluetooth mouse to become unusable.

The problem is that the mouse doesn't work with HID++ and so it needs to be
added to the list of "unhandled" devices in logitech-hidpp (patch 2), but
this is not sufficient, because hid-generic needs to actually check whether
other drivers have ->match callbacks and what those callbacks return for
the given device (patch 1).

Thanks!
