From 51e20d0e3a60cf46b52ee1af598a35834919ed27 Mon Sep 17 00:00:00 2001 From: "Rafael J. Wysocki" Date: Sun, 6 Nov 2011 14:21:38 +0100 Subject: [PATCH] thermal: Prevent polling from happening during system suspend The thermal driver should use a freezable workqueue to schedule polling to prevent thermal_zone_device_update() from being run during system suspend, when the devices it relies on may be inactive. Make it use the system freezable workqueue for this purpose. Signed-off-by: Rafael J.
