    Input: libps2 - relax command byte ACK handling · 29acc42e
    Dmitry Torokhov authored
    When we probe PS/2 devices we first issue "Get ID" command and only if we
    receive what we consider a valid keyboard or mouse ID we disable the device
    and continue with protocol detection. That means that the device may be
    transmitting motion or keystroke data, while we expect ACK response.
    
    Instead of signaling failure if we see anything but ACK/NAK let's ignore
    "garbage" response until we see ACK for the command byte (first byte). The
    checks for subsequent ACKs of command parameters will continue be strict.
