These are mostly false positives, the clang-analyzer FAQ[1] specifies
why and how to fix it:
> The reason the analyzer often thinks that a pointer can be null is
> because the preceding code checked compared it against null. So if you
> are absolutely sure that it cannot be null, remove the preceding check
> and, preferably, add an assertion as well.
