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. -- Dmitry
