Date: Thu, 25 Dec 2008 03:45:25 +0100 From: "Krzysztof Kosiński" <tweenk.pl@...il.com> To: linux-kernel@...r.kernel.org Cc: carlos@...angeworlds.co.uk Subject: [PATCH] tc1100-wmi: fix state reporting This small patch fixes the state reported when reading the files in /sys/devices/platofrm/tc1100-wmi/*. The first change fixes always returning 0 from the files in sysfs. The second one fixes jogdial state reprting to match with the commands used to set it (e.g. now after "echo 0 > /sys/devices/platofrm/tc1100-wmi/jogdial", "cat /sys/devices/platofrm/tc1100-wmi/jogdial" will return 0 instead of 1). Please CC any replies to me (I'm not subscribed).
