[v4, 1/9] ACPI / PM: Let acpi_dev_pm_detach() return an error code

Hi Ulf,

To give callers the option of acting on a errors while removing the
pm_domain ops for the device in the ACPI PM domain, let
acpi_dev_pm_detach() return an int to provide the error code.

So how would callers handle the errors? As far as I can see
acpi_dev_pm_detach() is called from ->remove() and ->shutdown() methods, where
there is no meaningful strategy to handle errors as you are past the point of
no return and you keep on tearing down the device.

Thanks.
