    HID: fixup quirk for NCR devices · 5b915d9e
    Jiri Kosina authored
    NCR devices are terminally broken by design -- they claim themselves to contain
    proper input applications in their HID report descriptor, but behave very badly
    if treated in standard way.
    
    According to NCR developers, the devices get confused when queried for reports
    in a standard way, rendering them unusable.
    
    NCR is shipping application called "RPSL" that can be used to drive these
    devices through hiddev, under the assumption that in-kernel driver doesn't
    perform initial report query.
    If it does, neither in-kernel nor hiddev-based driver can operate with these
    devices any more.
    
    Introduce a quirk that skips the report query for all NCR devices. The previous
    NOGET quirk was wrong and had been introduced because I misunderstood the nature
    of brokenness of these devices.
