Are you using the latest commit? There was a minor change missing regarding the line discipline parameter. If you use the latest version and still get this error please post the output of 

sudo dmesg
Ciusss89 commented 4 years ago

you've right

[346107.881006] hlcan: QinHeng serial line CAN interface driver
[346107.881008] hlcan: 10 dynamic interface channels.
[346107.881009] hlcan: can't register line discipline

What kernel are you using? The module loading is working with 5.5.13
