[PATCH v3 3/4] ACPI / x86-utils: Remove status workaround from acpi_device_always_present()

Hans de Goede
2018-08-07T08:05:38Z

Now that we init the status field to ACPI_STA_DEFAULT rather then to 0,
the workaround for acpi_match_device_ids() always returning -ENOENT when
status is 0 is no longer needed.
