     * Relax the source check on this test because we encountered a Linux kernel behavior change in
     * 4.18 or later that splits the device into multiple devices according to its applications in
     * HID descriptor. That change further lets Android framework split the KeyboardInputMapper
     * because it thinks they are different devices which in turn split the source flags. Therefore
     * we relax the test so that it can pass with both behaviors until we reach a consensus with
     * upstream Linux on the desired behavior.
