[PATCH 4.9 101/152] HID: usbhid: Add quirk for Mayflash/Dragonrise DolphinBar.

[Greg Kroah-Hartman]

4.9-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Marcel Hasler <mahasler@xxxxxxxxx>

[ Upstream commit 8aa2cc7e747881d1fd52db28261b201d4e3e5565 ]

The DolphinBar by Mayflash (identified as Dragonrise) needs
HID_QUIRK_MULTI_INPUT to split it up into four input devices. Without this
quirk the adapter is falsely recognized as a tablet. See also bug 115841
(https://bugzilla.kernel.org/show_bug.cgi?id=115841).
