From f635bd11c8d332d917fb9a4cad3071b2357d5b2a Mon Sep 17 00:00:00 2001 From: Henrik Rydberg Date: Thu, 24 Feb 2011 19:30:59 +0100 Subject: HID: Do not create input devices for feature reports When the multi input quirk is set, there is a new input device created for every feature report. Since the idea is to present features per hid device, not per input device, revert back to the original report loop and change the feature_mapping() callback to not take the input device as argument.
