Merge tag 'pm-for-3.6-rc2' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm
Pull power management fixes from Rafael J. Wysocki:
- Fix for two recent regressions in the generic PM domains framework.
- Revert of a commit that introduced a resume regression and is
conceptually incorrect in my opinion.
- Fix for a return value in pcc-cpufreq.c from Julia Lawall.
- RTC wakeup signaling fix from Neil Brown.
- Suppression of compiler warnings for CONFIG_PM_SLEEP unset in ACPI,
platform/x86 and TPM drivers.
