Pull ACPI & Thermal updates from Len Brown:
 "The generic Linux thermal layer is gaining some new capabilities
  (generic cooling via cpufreq) and some new customers (ARM).

  Also, an ACPI EC bug fix plus a regression fix."

* 'release' of git://git.kernel.org/pub/scm/linux/kernel/git/lenb/linux: (30 commits)
  tools/power/acpi/acpidump: remove duplicated include from acpidump.c
  ACPI idle, CPU hotplug: Fix NULL pointer dereference during hotplug
  cpuidle / ACPI: fix potential NULL pointer dereference
  ACPI: EC: Add a quirk for CLEVO M720T/M730T laptop
  ACPI: EC: Make the GPE storm threshold a module parameter
  thermal: Exynos: Fix NULL pointer dereference in exynos_unregister_thermal()
  Thermal: Fix bug on cpu_cooling, cooling device's id conflict problem.
  thermal: exynos: Use devm_* functions
  ARM: exynos: add thermal sensor driver platform data support
  thermal: exynos: register the tmu sensor with the kernel thermal layer
  thermal: exynos5: add exynos5250 thermal sensor driver support
  hwmon: exynos4: move thermal sensor driver to driver/thermal directory
  thermal: add generic cpufreq cooling implementation
  Fix a build error.
  thermal: Fix potential NULL pointer accesses
  thermal: add Renesas R-Car thermal sensor support
  thermal: fix potential out-of-bounds memory access
  Thermal: Introduce locking for cdev.thermal_instances list.
  Thermal: Unify the code for both active and passive cooling
  Thermal: Introduce simple arbitrator for setting device cooling state
