From: Jiri <jiri.prchal@xxxxxxxxxxx>
If led-always-blink is set, then between switch led OFF and ON
is almost zero time. So blink is invisible. This use oneshot led trigger
with fixed time 50ms witch is enough to see blink.
Signed-off-by: Jiri <jiri.prchal@xxxxxxxxxxx>
v2:
defined constant XT_LED_BLINK_DELAY and use it instead of number
Hope this time sould be OK.
