From: Benjamin Tisssoires <benjamin.tissoires@redhat.com>
This allows the transport layer (I have in mind hid-logitech-dj and uhid) to set the group before it is added to the hid bus. This way, it can bypass the hid_scan_report() call, and choose in advance which driver will handle the newly created hid device.
