I'm sorry but you probably need another revision.

And don't feel embarrassed, I mean this is your first patch
in the kernel and that's an IIO driver!!

I used to fix spelling mistakes, align parameters, ... an year ago
and even those got rejected several times ;)

Obligations!

Just don't go "Keyser Söze" once you're done with your major
at University. You would need to test/review patches in future.

Not a big deal though..

MODULE_DEVICE_TABLE(of, st_vl53l0x_dt_match); ?
