ACPI: Change acpi_device_always_present() into acpi_device_override_status()
Currently, acpi_bus_get_status() calls acpi_device_always_present() to allow platform quirks to override the _STA return to report that a device is present (status = ACPI_STA_DEFAULT) independent of the _STA return. In some cases it might also be useful to have the opposite functionality and have a platform quirk which marks a device as not present (status = 0) to work around ACPI table bugs. Change acpi_device_always_present() into a more generic acpi_device_override_status() function to allow this. Signed-off-by: Hans de Goede <hdegoede@redhat.com> Signed-off-by: Rafael J.
