Pull ACPI and power management fixes from Rafael Wysocki:
"These are three stable-candidate fixes, one for the ACPI thermal
driver and two for cpufreq drivers.
Specifics:
- A workqueue is destroyed too early during the ACPI thermal driver
module unload which leads to a NULL pointer dereference in the
driver's remove callback. Fix from Aaron Lu.
- A wrong argument is passed to devm_regulator_get_optional() in the
probe routine of the cpu0 cpufreq driver which leads to resource
leaks if the driver is unbound from the cpufreq platform device.
Fix from Lucas Stach.
- A lock is missing in cpufreq_governor_dbs() which leads to memory
corruption and NULL pointer dereferences during system
suspend/resume, for example. Fix from Bibek Basu"
