v3: * Add a new power.force_direct_complete to let devices express that it's safe to let them be runtime-suspended at system sleep regardless of the state of their descendants
v2: * Let creators of the input device to decide whether it should remain runtime suspended when the system goes into a sleep state * Don't enable PM runtime on all evdev handlers * Cope with another wrong wakeup setting in usb_dev_prepare
Hi,
this series contain what I needed to do in order to have my USB webcam to not be resumed when the system resumes, reducing considerably the total time that resuming takes.
It makes use of the facility that Rafael Wysocki added in aae4518b3 ("PM / sleep: Mechanism to avoid resuming runtime-suspended devices unnecessarily").
Thanks,
Tomeu
