Rafael J. Wysocki	e1b1903eee	PM / Runtime: Make documentation of runtime_idle() agree with the code ... Currently the ->runtime_idle() callback is documented as having no return value, but in fact it returns int. Although its return value is ignored at the PM core level, it may be used by bus type routines executing the drivers' ->runtime_idle() callbacks. Signed-off-by: Rafael J.

Rafael J. Wysocki	5e928f77a0	PM: Introduce core framework for run-time PM of I/O devices (rev. 17) ... Introduce a core framework for run-time power management of I/O devices. Add device run-time PM fields to 'struct dev_pm_info' and device run-time PM callbacks to 'struct dev_pm_ops'. Introduce a run-time PM workqueue and define some device run-time PM helper functions at the core level. Document all these things. Special thanks to Alan Stern for his help with the design and multiple detailed reviews of the pereceding versions of this patch and to Magnus Damm for testing feedback. Signed-off-by: Rafael J.
