From 89bdd0c6f38ccf0de43d5a36ede384a730f3394e Mon Sep 17 00:00:00 2001 From: David Herrmann Date: Mon, 18 Feb 2013 01:47:15 +0100 Subject: [PATCH] HID: wiimote: fix nunchuck button parser The buttons of the Wii Remote Nunchuck extension are actually active low. Fix the parser to forward the inverted values. The comment in the function always said "0 == pressed" but the implementation was wrong from the beginning.
