Y. Srinivasan" List-Id: virtualization@lists.linuxfoundation.org Set the hid drvdata prior to invoking hid_add_device() as hid_add_device() expects this state to be set. This bug was introduced in the recent hid changes that were made in: commit 07d9ab4f0e52cb2a383596e5ebbbd20232501393 HID: hid-hyperv: Do not use hid_parse_report() directly Signed-off-by: K. Y.
