More power management updates for 3.4 Fixes mostly, including: * Patch series that hopefully fixes races between the freezer and request_firmware() and request_firmware_nowait() for good, with two cleanups from Stephen Boyd on top. * Runtime PM fix from Alan Stern preventing tasks from getting stuck indefinitely in the runtime PM wait queue. * Device PM QoS update from MyungJoo Ham introducing a new variant of pm_qos_update_request() allowing the callers to specify a timeout.
