[PATCH] leds: turn LED off when changing triggers
I was playing with LED triggers when I noticed that changing from heartbeat (or ide-disk) to "none" at the right moment would leave the LED stuck on. This is easy to reproduce by doing "find / >/dev/null" with the ide-disk trigger enabled and then switching to "none". Here is a patch that fixes the problem by explicitly turning the LED off after removing the existing trigger.
