Merge branch 'next' of git://git.kernel.org/pub/scm/linux/kernel/git/rzhang/linux
Pull thermal management fixes from Zhang Rui: - Power allocator governor changes to allow binding on thermal zones with missing power estimates information. From Javi Merino. - Add compile test flags on thermal drivers that allow it without producing compilation errors. From Eduardo Valentin. - Fixes around memory allocation on cpu_cooling. From Javi Merino. - Fix on db8500 cpufreq code to allow autoload. From Luis de Bethencourt. - Maintainer entries for cpu cooling device * 'next' of git://git.kernel.org/pub/scm/linux/kernel/git/rzhang/linux: thermal: power_allocator: exit early if there are no cooling devices thermal: power_allocator: don't require tzp to be present for the thermal zone thermal: power_allocator: relax the requirement of two passive trip points thermal: power_allocator: relax the requirement of a sustainable_power in tzp thermal: Add a function to get the minimum power thermal: cpu_cooling: free power table on error or when unregistering thermal: cpu_cooling: don't call kcalloc() under rcu_read_lock thermal: db8500_cpufreq_cooling: Fix module autoload for OF platform driver thermal: cpu_cooling: Add MAINTAINERS entry thermal: ti-soc: Kconfig fix to avoid menu showing wrongly thermal: ti-soc: allow compile test thermal: qcom_spmi: allow compile test thermal: exynos: allow compile test thermal: armada: allow compile test thermal: dove: allow compile test thermal: kirkwood: allow compile test thermal: rockchip: allow compile test thermal: spear: allow compile test thermal: hisi: allow compile test thermal: Fix thermal_zone_of_sensor_register to match documentation
