Merge branch 'pm-core'
* pm-core:
driver core: Avoid NULL pointer dereferences in device_is_bound()
platform: Do not detach from PM domains on shutdown
USB / PM: Allow USB devices to remain runtime-suspended when sleeping
PM / sleep: Go direct_complete if driver has no callbacks
PM / Domains: add setter for dev.pm_domain
device core: add device_is_bound()
