Patch for drivers/usb/serial/ch341.c enabling parity

[Leif Neland]

There is a patch

https://github.com/karlp/ch341-linux/blob/master/0001-usb-serial-ch341-Add-parity-support.patch

which enables parity selection for the ch341 USB-RS485 adapter.

This adapter is available for cheap on eBay.

The patch made me able to use this adapter for polling my modbus
power-meter with raspberry pi.

Would it be possible to get this into the official distribution?
