Subject: [patch] usb/serial/ssu100: uninitialized variable

GCC complains about the original code, because we're using an
unintialized variable "flag".  I think we should be setting flag based
on the UART_LSR_BRK_ERROR_BITS but I'm not sure...  I don't have this
hardware.  Probably passing TTY_NORMAL is better than the current code?
