Subject: [PATCH] HID: hyperv: Set the hid drvdata correctly
Git-commit: b565a3906a92fe87b162cdcd11268589a36dc6dd
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 07d9ab4f0e52cb ("HID: hid-hyperv: Do not use
hid_parse_report() directly").
