From ee286c2e80547d87ed4e55c00709783aa2261848 Mon Sep 17 00:00:00 2001 From: David Herrmann Date: Sun, 26 May 2013 22:55:04 +0200 Subject: HID: wiimote: fix classic controller parsing I finally got a "Classic Controller" and "Classic Controller Pro" in my hands and noticed that all analog data was incorrectly parsed. Fix this up so we report the data that we pretend we do. I really doubt that this breaks any backwards compatibility, but if we get any reports, we only need to revert this single patch.
