Libor Pechacek 6fe7015007 USB: serial: handle Data Carrier Detect changes ... commit d14fc1a74e upstream. Alan's commit 335f8514f2 introduced .carrier_raised function in several drivers. That also means tty_port_block_til_ready can now suspend the process trying to open the serial port when Carrier Detect is low and put it into tty_port.open_wait queue. We need to wake up the process when Carrier Detect goes high and trigger TTY hangup when CD goes low. Some of the devices do not report modem status line changes, or at least we don't understand the status message, so for those we remove .carrier_raised again.
