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"
