What version of gcc you are using? Your gcc doesn't understand the two commandline options '-mgeneral-regs-only' and '-mcmodel=large'
I'm on 6.0.0-1164-ayufan and compiling with gcc 13.1.1 that driver works like a charm:
Code:$ make
make -C /lib/modules/6.0.0-1164-ayufan-ga2fd0c498/build M=/tmp/CH341SER_LINUX/driver
make[1]: Entering directory '/usr/src/linux-headers-6.0.0-1164-ayufan-ga2fd0c498'

That driver loads into that kernel without complaint:
[ 152.041600] ch341: loading out-of-tree module taints kernel.
[ 152.042335] usbcore: registered new interface driver usb_ch341

[ 152.042344] ch341: V1.6 On 2022.08
May be is is incompatible with the legacy kernel?
I still get the same error after updating gcc to gcc-9 following this tutorial: How to Install GCC Compiler on Ubuntu 18.04 | Linuxize
