Title:
  ch341 usb serial converter kernel driver parity patch missing

Status in linux package in Ubuntu:
  Triaged

Bug description:
  I have several pieces of this cheap Chinese USB2serial port converter,
  which uses ch341.ko kernel module.

  By default / fault, the parity function of this chip is not implemented in the kernel driver.
  This causes that the converter is UNUSABLE on ubuntu linux 14.04 (latest updates installed, default kernel, current version 3.13.0-88-generic)
  There is a fix for that, applying that patch makes it work as it should be. 

  All current ubuntu kernels miss this patch:
  http://blog.xentoo.info/2015/12/31/ubuntu-14-04-and-usb-to-serial-ch341-chinese-device-from-ebay/

  I have to recompile the kernel module ch341.ko every time when new kernel version is installed.
  It seems to me while googling this, that somehow this fix haven't got into mainstream kernel.

  Please include this patch to all ubuntu kernel versions!
  Thank you!
