Merge tag 'pm+acpi-3.12-rc5' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm

Pull ACPI and power management fixes from Rafael Wysocki:
 "These fix two recent bugs in ACPIPHP (ACPI-based PCI hotplug) and
  update a bunch of web links and e-mail addresses in MAINTAINERS, docs
  and Kconfig that either are stale or will expire soon.

  Specifics:

   - The WARN_ON() in acpiphp_enumerate_slots() triggers as a false
     positive in some cases, so drop it.

   - Add a missing pci_dev_put() to an error code path in
     acpiphp_enumerate_slots().

   - Replace my old e-mail address that's going to expire with a new
     one.

   - Update ACPI web links and git tree information in MAINTAINERS.

   - Update links to the Linux-ACPI project's page in MAINTAINERS.

   - Update some stale links and e-mail addresses under Documentation
     and in the ACPI Kconfig file"
