[Patch-V2 5/6] HID: Add vendor specific usage pages for Logitech G920

From: Simon Wood
Date: Thu Nov 12 2015 - 11:26:31 EST


The Logitech G920 uses a couple of vendor specific usage pages,
which results in incorrect number of axis/buttons being detected.

This patch adds these pages to the 'ignore' list.
