compile error - incompatible pointer type

I'm facing many warnings and one error when running make all -

This looks the same as an issue on another repo, link

I am having the same problem with Kernel: 6.8.0-41-generic

I am using "sudo make all" to build on Kernel 6.8.0-40-generic. I am also having this same build issue - relevant part from make output:
