I realize now that my last patch broke ledtrig-timer updates as that
works by passing delay_{on,off} values by pointer, and moving
led_stop_software_blink() earlier destroy the other value.

That's a bit of a pitfall, as the old code was working because values
were copied when entering led_set_software_blink.

I see three options here:
- reverting back my leds: "fix led_brightness_set when soft-blinking"
(9b05cd0) to the first version I posted, wich should work as before.
- modify ledtrig-timer to use two internal variables to store delay_on
and delay_off instead of the led_cdev ones.
- moving the two led_cdev->blink_delay_xx = 0 only into
led_brightness_set, as that's the only place when they are needed.

What you think about it?

I think the third option is the best, as it removes the pitfall and
simplify the code a bit. I'll post that as a v3 "fix led_brightness_set
when soft-blinking", would you consider replacing the last patch you
applied in the new branch with the v3?

Fabio
