1243          *      alt_speed==0, (or)
1244          *    - call TIOCSSERIAL ioctl with (struct serial_struct) set as

1248          *      SHI: 230400, WARP: 460800)
1249          * ** Steps 1, 2 are done courtesy of tty_get_baud_rate
1250          * 3. You can also set baud rate by setting custom divisor as follows
1251          *    - set tty->termios->c_cflag speed to B38400
1252          *    - call TIOCSSERIAL ioctl with (struct serial_struct) set as
1253          *      follows:

1255          *      o custom_divisor set to baud_base / your_new_baudrate
1256          * ** Step 3 is done courtesy of code borrowed from serial.c
1257          *    I should really spend some time and separate + move this common
1258          *    code to serial.c, it is replicated in nearly every serial driver
