    clang static analysis reports this problem
    
    b53_common.c:1583:13: warning: The left expression of the compound
      assignment is an uninitialized value. The computed value will
      also be garbage
            ent.port &= ~BIT(port);
            ~~~~~~~~ ^
    
    ent is set by a successful call to b53_arl_read().  Unsuccessful
    calls are caught by an switch statement handling specific returns.
    b32_arl_read() calls b53_arl_op_wait() which fails with the
    unhandled -ETIMEDOUT.
    
    So add -ETIMEDOUT to the switch statement.  Because
    b53_arl_op_wait() already prints out a message, do not add another
    one.
