Does not compile with kernel 6.8.0

[rowlo]

I've linux headers and kernel module build dependencies installed on ubuntu 24.04 LTS.

Calling make gives me this error:

>$ make
make -C /lib/modules/6.8.0-51-generic/build  M=/home/xxx/devel/github/ELEGOO Smart Robot Car Kit V4.0 2024.01.30/01 ReadMeFirst/CH340 Driver Software/ch341ser_linux-main/driver
