I am not able to compile the driver ch34x.ko

[LuSochr]

Hi to All, one desperate soul here. I need to install this driver and I followed the instructions in Aperepel's page. One minute how-to didn't work because I have different kernel. So if I try to do insmod i receive error stating that Invalid module format - that was expected. So I prepared everything for make command (linux headers, updates etc.) but I am still receiving this error about invalid datapointers:

C is way above my programming skills, so I am looking for help everywhere but without any luck. Any help would be highly appreciated...

THanks!!!

I'm getting the same error on 6.1.x kernel. On both X64 and AARCH64
