Description

Haven't done an exhaustive review, seems like the codebase is correct in terms of "check before doing things", but the checks didn't account for users providing NULL pointers to the functions. Thus MCU would crash when checking if (!pointer->valid), now we do if (!pointer || !pointer->valid)

Perhaps should have targeted master... 🤔

Shall i add my name to headers after such a tiny change?
