I'm trying to port my Oneplus kernel, and it's also my first time compiling a kernel.
I've attached a screenshot.
It says it compiles successfully, but the errors seem valid enough to address.

I git cloned my sm6350 device then git cloned the Nethunter kernel builder inside that directory.
I used the empty local.config.example to let the default .config manage, not sure if thats correct.

What do you make of these errors?
