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.
