[PATCH 4.9 100/105] HID: ignore Petzl USB headlamp

[Greg Kroah-Hartman]

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

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

From: Jiri Kosina <jkosina@xxxxxxx>


[ Upstream commit 08f9572671c8047e7234cbf150869aa3c3d59a97 ]

This headlamp contains a dummy HID descriptor which pretends to be
a mouse-like device, but can't be used as a mouse at all.
