[ 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").
Fixes: e0a5172e9eec7f0d ("thermal: rcar: add interrupt support")
