HID: thingm: remove the "fade" sysfs attribute
As for the "play" sysfs attribute, remove this other non-standard attribute, so the driver only implements what is required to switch the LED on and off. Thus, a fade time won't be ideal for some fast-changing triggers. Signed-off-by: Vivien Didelot <vivien.didelot@savoirfairelinux.com> Signed-off-by: Jiri Kosina <jkosina@suse.cz>
