    Input: soc_button_array - add invalid acpi_index DMI quirk handling · 20a99a29
    Hans de Goede authored May 11, 2023
    
    
    Some devices have a wrong entry in their button array which points to
    a GPIO which is required in another driver, so soc_button_array must
    not claim it.
    
    A specific example of this is the Lenovo Yoga Book X90F / X90L,
    where the PNP0C40 home button entry points to a GPIO which is not
    a home button and which is required by the lenovo-yogabook driver.
    
    Add a DMI quirk table which can specify an ACPI GPIO resource index which
    should be skipped; and add an entry for the Lenovo Yoga Book X90F / X90L
    to this new DMI quirk table.
