From 5ca0cce5622bf476e3e6bf627fe8e9381d6ae174 Mon Sep 17 00:00:00 2001 From: Ni Wade Date: Mon, 17 Feb 2014 11:02:55 +0800 Subject: Thermal: Allow first update of cooling device state In initialization, if the cooling device is initialized at max cooling state, and the thermal zone temperature is below the first trip point, then the cooling state can't be updated to the right state, untill the first trip point be triggered. To fix this issue, allow first update of cooling device state during registration, initialized "updated" device field as "false" (instead of "true").
