Pull ACPI and power management fixes from Rafael Wysocki: "These are regression fixes (ACPI hotplug, cpufreq, hibernation, ACPI LPSS driver), fixes for stuff that never worked correctly (ACPI GPIO support in some cases and a wrong sign of an error code in the ACPI core in one place), and one blacklist item for ACPI backlight handling. Specifics: - Revert of a recent hibernation core commit that introduced a NULL pointer dereference during resume for at least one user (Rafael J Wysocki). - Fix for the ACPI LPSS (Low-Power Subsystem) driver to disable asynchronous PM callback execution for LPSS devices during system suspend/resume (introduced in 3.16) which turns out to break ordering expectations on some systems. From Fu Zhonghui. - cpufreq core fix related to the handling of sysfs nodes during system suspend/resume that has been broken for intel_pstate since 3.15 from Lan Tianyu. - Restore the generation of "online" uevents for ACPI container devices that was removed in 3.14, but some user space utilities turn out to need them (Rafael J Wysocki). - The cpufreq core fails to release a lock in an error code path after changes made in 3.14. Fix from Prarit Bhargava. - ACPICA and ACPI/GPIO fixes to make the handling of ACPI GPIO operation regions (which means AML using GPIOs) work correctly in all cases from Bob Moore and Srinivas Pandruvada. - Fix for a wrong sign of the ACPI core's create_modalias() return value in case of an error from Mika Westerberg. - ACPI backlight blacklist entry for ThinkPad X201s from Aaron Lu" * tag 'pm+acpi-3.17-rc7' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm: Revert "PM / Hibernate: Iterate over set bits instead of PFNs in swsusp_free()" gpio / ACPI: Use pin index and bit length ACPICA: Update to GPIO region handler interface. ACPI / platform / LPSS: disable async suspend/resume of LPSS devices cpufreq: release policy->rwsem on error cpufreq: fix cpufreq suspend/resume for intel_pstate ACPI / scan: Correct error return value of create_modalias() ACPI / video: disable native backlight for ThinkPad X201s ACPI / hotplug: Generate online uevents for ACPI containers
