In order to communicate with the correct IPMI device, it should be confirmed whether it is what we wanted especially on the system with multiple IPMI devices. But the new_smi callback function of smi_watcher provides very limited info(only the interface number and dev pointer) and there is no detailed info about the low level interface. For example: which mechansim registers the IPMI interface(ACPI, PCI, DMI and so on). This is to add one interface that can get more info of low-level IPMI device. For example: the ACPI device handle will be returned for the pnp_acpi IPMI device.
