Grygorii Strashko reports:
The PM runtime will be left disabled for the device if its
.suspend_late() callback fails and async suspend is not allowed
for this device. In this case device will not be added in
dpm_late_early_list and dpm_resume_early() will ignore this
device, as result PM runtime will be disabled for it forever
(side effect: after 8 subsequent failures for the same device
the PM runtime will be reenabled due to disable_depth overflow).
To fix this problem, add devices to dpm_late_early_list regardless
of whether or not device_suspend_late() returns errors for them.
That will ensure failures in there to be handled consistently for
all devices regardless of their async suspend/resume status.
