[ Upstream commit 3a31386217628ffe2491695be2db933c25dde785 ]
On r8a7791/koelsch, sometimes the following message is printed during system suspend:
rcar_thermal e61f0000.thermal: thermal sensor was broken
This happens if the workqueue runs while the device is already suspended. Fix this by using the freezable system workqueue instead, cfr. commit 51e20d0e3a60cf46 ("thermal: Prevent polling from happening during system suspend").
