    USB: cdc-acm: Do not log urb submission errors on disconnect · f0386c08
    Hans de Goede authored
    When disconnected sometimes the cdc-acm driver logs errors like these:
    
    [20278.039417] cdc_acm 2-2:2.1: urb 9 failed submission with -19
    [20278.042924] cdc_acm 2-2:2.1: urb 10 failed submission with -19
    [20278.046449] cdc_acm 2-2:2.1: urb 11 failed submission with -19
    [20278.049920] cdc_acm 2-2:2.1: urb 12 failed submission with -19
    [20278.053442] cdc_acm 2-2:2.1: urb 13 failed submission with -19
    [20278.056915] cdc_acm 2-2:2.1: urb 14 failed submission with -19
    [20278.060418] cdc_acm 2-2:2.1: urb 15 failed submission with -19
    
    Silence these by not logging errors when the result is -ENODEV.
