The above compilation error happened on last ubuntu 22.04 update. It was compiled successfully a month ago. Please, fix this issue!

This small patch fix the compilation problem on kernel 6.5.0 (Ubuntu 23.10), it is working afterwards but I'm not sure at all about implications.
Will try to use it a bit and see.

Side note: while compiling, there are quite some warnings now, not sure which ones are real and which ones are not, I'll try to take a look if and when my little knowledge assists me.
