From 3767cb54ac718eb049d2a29f7a575ab923550ba5 Mon Sep 17 00:00:00 2001 From: Frans Pop Date: Mon, 26 Oct 2009 08:39:04 +0100 Subject: thermal: disable polling if passive_delay and polling_delay are both unset Otherwise polling will continue for the thermal zone even when it is no longer needed, for example because forced passive cooling was disabled.
