This series patch V7 is changed from V6 as following:

1. The buffer of usb_control_msg() in set_register()/get_register() are change
   from local variable to kmalloc(). (PATCH V7 02/11)
2. Change all set_register()/get_register() return value 0 is success, 
   otherwise are failed. ( return 0 of usb_control_msg() treat as -EIO, 
   PATCH V7 02/11)
3. tty_port_tty_get() called only when DCD has changed. (PATCH V7 05/11)  
4. remove likely()/unlikely() branch prediction.
5. Implement DTR/RTS control when baudrate B0. We drop DTR/RTS when B0, 
   otherwise enable it. (PATCH V7 08/11)
6. Change private struct line_control to modem_control with meanful. 
   (PATCH V7 06/11)
7. We confirmd MSR strange delta value is not locking-issue. The issue
   maybe reproduce with set MCR & get MSR before IIR notice with MSR changed.
   
V6 (old change):

1. transform all function not to use private data as parameter, using
   usb_serial_port instead.
2. process_read_urb() add process of Break/FrameError/ParityError/OE.
   (patch: 03/10)
3. fix calc_baud_divisor() will cause divide by zero with B0. (patch: 04/10)
4. Some init step we extract it from set_termios() to f81232_port_init()
   and run it when open port only. (patch: 04/10)
5. We'll force re-read msr in tiocmget() because the IIR with MSR change
   maybe delay received. (patch: 05/10)
6. fix MSR status bits changed but delta bits is 0 will cause read serial port
   malfunctional with update port status. (patch: 08/10)
7. Add MSR change statistic when MSR has been read. (patch: 09/10)   
8. clarify a lot of code about Johan suggested.
