Re: [PATCH 2/2] leds: trigger: ledtrig-tty: add additional modes

I thought about that before implementing this patch set, but then I 
discarded it.
Coding several states would then become confusing for someone who look 
at the LED.
I have now consciously decided that I want only display one state.
