    usb-serial: straighten out serial_open · 320348c8
    Alan Stern authored
    This patch (as1291) removes a bunch of code from serial_open(), things
    that were rendered unnecessary by earlier patches.  A missing spinlock
    is added to protect port->port.count, which needs to be incremented
    even if the open fails but not if the tty has gotten a hangup.  The
    test for whether the hardware has been initialized, based on the use
    count, is replaced by a more transparent test of the
    ASYNCB_INITIALIZED bit in the port flags.
