Merge tag 'pm-4.16-rc2' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm
Pull power management fixes from Rafael Wysocki: "These fix a recently introduced build issue related to cpuidle and two bugs in the PM core, update cpuidle documentation and clean up memory allocations in the operating performance points (OPP) framework. Specifics: - Fix a recently introduced build issue related to cpuidle by covering all of the relevant combinations of Kconfig options in its header (Rafael Wysocki). - Add missing invocation of pm_runtime_drop_link() to the !CONFIG_SRCU variant of __device_link_del() (Lukas Wunner). - Fix unbalanced IRQ enable in the wakeup interrupts framework (Tony Lindgren). - Update cpuidle sysfs ABI documentation (Aishwarya Pant). - Use GFP_KERNEL instead of GFP_ATOMIC for allocating memory in dev_pm_opp_init_cpufreq_table() (Jia-Ju Bai)" * tag 'pm-4.16-rc2' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm: PM: cpuidle: Fix cpuidle_poll_state_init() prototype PM / runtime: Update links_count also if !CONFIG_SRCU PM / wakeirq: Fix unbalanced IRQ enable for wakeirq Documentation/ABI: update cpuidle sysfs documentation opp: cpu: Replace GFP_ATOMIC with GFP_KERNEL in dev_pm_opp_init_cpufreq_table
