Merge tag 'pm+acpi-3.17-rc5' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm
Pull ACPI and power management fixes from Rafael Wysocki: "These are regression fixes (cpufreq, ACPI battery) and fixes for stuff that never worked correctly (ACPI RTC operation region handler and PM domain implementation in the ACPI LPSS driver). Specifics: - Fix for the cpufreq Operation Performance Points (OPP) code where a recent commit added a kcalloc() call with an incorrect ordering of arguments. From Anand Moon. - Reverts of two ACPI battery commits that caused incorrect diagnostic information to be printed to dmesg in some cases from Bjørn Mork. - Fix for the ACPI RTC operation region handler that applied the & operator to an argument already representing an address and that caused it to overwrite its own argument instead of writing to the address contained in it as expected. From Chun-Yi Lee. - Fix for the PM domain implementation in the ACPI LPSS (Low-Power Subsystem) driver where one callback pointer pointed to a wrong routine and one was NULL, but it shouldn't. From Fu Zhonghui" * tag 'pm+acpi-3.17-rc5' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm: ACPI / LPSS: complete PM entries for LPSS power domain Revert "ACPI / battery: fix wrong value of capacity_now reported when fully charged" Revert "ACPI / battery: Fix warning message in acpi_battery_get_state()" ACPI / RTC: Fix CMOS RTC opregion handler accesses to wrong addresses cpufreq / OPP: Fix the order of arguments for kcalloc()
