[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.
