First of all: I compiled and the program is built without problems:

lucjan@archlinux ~/Pobrane/roboczy/roboczy-2/CH341SER $ export LANG=c
lucjan@archlinux ~/Pobrane/roboczy/roboczy-2/CH341SER $ make
make -C /lib/modules/5.8.11.ll27-1-lucjan-git/build  M=/home/lucjan/Pobrane/roboczy/roboczy-2/CH341SER

Secondly: Why do you compile on your root account? This is highly inadvisable.

Thirdly: Check on another gcc version, you have a bit out of date (the latest of the gcc8 line is 8.4).
