Subject[PATCH 1/1] Drivers: hid: hid-hyperv: Implement a stub raw_request() entry point
Date
commit 3c86726cfe38952f0366f86acfbbb025813ec1c2
Author: Benjamin Tissoires <benjamin.tissoires@redhat.com>

HID: make .raw_request mandatory

SET_REPORT and GET_REPORT are mandatory in the HID specification.
Make the corresponding API in hid-core mandatory too, which removes the
need to test against it in some various places.

Made .raw_request mandatory and broke the Hyper-V mouse driver. This patch
fixes the problem.
