acpi_dev_get_first_match_dev() searches for an acpi_handle instantiated by the ACPI table scanning done early during boot.
Two of three machine drivers using this search don't deal with errors and the one which does (bytcr_rt5651) returns -ENODEV, which doesn't make sense here: an alternate driver will not be probed.
Add consistent error handling and report -ENXIO.
