    ACPI: scan: Add Intel Baytrail Mailbox Device to acpi_ignore_dep_ids · 9272e97a
    Hans de Goede authored
    Linux does not have a driver for / does not use the "Intel Baytrail
    Mailbox Device" (ACIP HID INT33BD). Add it to the acpi_ignore_dep_ids
    list, so that we do not defer probing ACPI devices which depend on
    another ACPI device with this HID.
    
    Specifically this makes us not defer the probing of the GPO1 ACPI
    device / GPIO controller on the Acer Switch 10E SW3-016. On this
    tablet model the  _HID method of the ACPI node for the UART attached
    Bluetooth, reads GPIOs to detect the installed wifi chip and updates
    the reported _HID for the Bluetooth's ACPI node accordingly.
    
    For the Bluetooth's ACPI node to report the correct _HID the GPO1 device
    must be probed and attached during the first scan pass. Adding the
    "INT33BD" HID to the acpi_ignore_dep_ids list makes this all work.
