Subject[RFC][PATCH 3/3] PM: Asynchronous suspend and resume for ACPI battery
Allow the ACPI battery device to be resumed and suspended

This only means that the driver's suspend and resume callbacks may
be executed in parallel with the callbacks of devices that don't
directly depend on the battery device (i.e. that are not its parent
or children).
