Merge branch 'release' of git://git.kernel.org/pub/scm/linux/kernel/git/lenb/linux
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
