WCH CH352 PCI-to-RS232 card bad default type

According to manufacture chip information from http://wch-ic.com/product/pci/ch352.asp type of emulated chip cannot be 16C550A (it is default value in linux and in patch https://lkml.org/lkml/2013/3/2/30 ). Correct value is 16550.
Therefore I need to run additional command
setserial /dev/ttySx uart 16550

Default value 16550A is not working, correct value 16550 is working on my PCI-RS232card.

Please somebody make changes to module drivers/tty/serial/8250/8250_pci.c (as I think).
