Umm... I am not sure what you meant. Let me clarify my comment. When
acpi_drv->ops.remove() failed, I thought we would need to roll-back the
procedure done by the acpi_device_remove_notify_handler() call, which I
indicated as "THIS CALL" above. So, in this error path, don't we need
something like below?
if (acpi_drv->ops.notify)
acpi_device_install_notify_handler(acpi_dev)
Thanks,
