I don't understand the fix.
The if sentence becomes true, when both acpi_device->driver and acpi_device->handler
are NULL. It means that acpi_eject_store() runs if either acpi_device->driver or
acpi_device->handler has pointer. Is it O.K.?
Yes.
I think it should be if (!acpi_device->driver || !acpi_device->handler).
No, the condition has to be "&&" because an acpi_device is _either_
bound to an ACPI driver or an ACPI scan handler.
Thank you for you clarification. I understood it.
