Is it valid to send events from within ->resume device method? If not, what=
 is=20
the proper way to notify user space about hardware changes during suspensio=
n?=20
Specifically it seems that new sysfs ACPI power supply interface sometimes=
=20
missing plugged in AC cord during suspend. I suspect that no event is=20
generated for this; I am not sure whether ACPI is required to generate such=
=20
events at all in this case.

I'll need some time to get reproducible case so I do not categorize this ye=
t=20
as regression.
