[PATCH V6 00/10] USB: f81232: V6 patches

[Peter Hung]

This series patch V6 is improvement from V5&V4 as following:

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.

Logs:

1. We had add dev_err() in set/get register function. Also add dev_err()
   in some function is to help us easily point out error position, so we
   still decide to remain it.

Thanks for reading.
