From ee85a4152516daf57ce1f05b16e5f06ab4f3cf91 Mon Sep 17 00:00:00 2001 From: Paul Kocialkowski Date: Sat, 27 Feb 2016 19:19:14 +0100 Subject: kc1: Power off when the power on reason is not a valid one Some power on reasons are not desirable (e.g. too short press on the power button), battery plug. Thus, power off the device when one of those occurs.
