during a system sleep, the thread no longer needs to be frozen.  It

The usb serial method set_termios() is called for the first time from
open() method in order to set up the termios structure with the default
device's settings, ignoring the current settings. Once it's initialized,
the next set_termios() calls will update the device with the
tty->termios settings.
Currently USB serial console code calls the driver open() method without
a tty and after that will allocate a fake tty and termios so the command
line arguments can be applied to the device
(console=ttyUSB0,115200,...). This makes the driver overwrite the
termios with the default settings and not applying the command line
options.

This patch changes usb_console_setup() to allocate the fake tty and
termios before the open() method is called.

When a usb serial adapter is used as console, the usb serial console
driver bumps the open_count on the port struct used but doesn't attach
a real tty to it (only a fake one temporaly). If this port is opened later
using the regular character device interface, the open method won't
initialize the port, which is the expected, and will receive a brand new
tty struct created by tty layer, which will be stored in port->tty.

When the last close is issued, open_count won't be 0 because of the
console usage and the port->tty will still contain the old tty value. This
is the last ttyUSB<n> close so the allocated tty will be freed by the
tty layer. The usb_serial and usb_serial_port are still in use by the
console, so port_free() won't be called (serial_close() ->
usb_serial_put() -> destroy_serial() -> port_free()), so the scheduled
work (port->work, usb_serial_port_work()) will still run. And
usb_serial_port_work() does:
(...)
        tty = port->tty;
        if (!tty)
                return;

        tty_wakeup(tty);
which causes (manually copied):

I work with a group of people on a free home automation tool called
FHEM.  Some of the users own more than one USB-serial device by ELV. The
ftdi_sio driver has most of the ELV devices disabled by default and
needs to be re-enabled every time you get a new kernel. Additionally a
new device (EM 1010 PC - enegry monitor) is missing in the list.
Currently our users have to follow the instructions we provide at
http://www.koeniglich.de/fhem/linux.html ... However, to some users it
is too complicated to compile their own kernel module.

We are aware that you can specify one additional device using the
vendor/product option of the module. But lot's of users own more than
one device.
