I've been meaning to merge David's patch and will get that done shortly,
sorry for the delay.

As I've said, I don't really think we need context flags for the LED
class at the moment. As you say, most of the triggers are atomic context
and those which can sleep are not time critical so I don't really see
the point in the added complexity.

Richard
