ACPI and power management fixes for 3.12-rc5
- 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.

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

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.
