1248          *      alt_speed==0, (or)
1249          *    - call TIOCSSERIAL ioctl with (struct serial_struct) set as

1253          *      SHI: 230400, WARP: 460800)
1254          * ** Steps 1, 2 are done courtesy of tty_get_baud_rate
1255          * 3. You can also set baud rate by setting custom divisor as follows
1256          *    - set tty->termios->c_cflag speed to B38400
1257          *    - call TIOCSSERIAL ioctl with (struct serial_struct) set as
1258          *      follows:

1260          *      o custom_divisor set to baud_base / your_new_baudrate
1261          * ** Step 3 is done courtesy of code borrowed from serial.c
1262          *    I should really spend some time and separate + move this common
1263          *    code to serial.c, it is replicated in nearly every serial driver
