readFile() can return uninitialized pointer on fopen() failure

Hi, I have a patch for this. Here's a ridiculous request. Can you add the "hacktoberfest" tag to your project? Regardless of whether the answer is yes or no, I'll send you the patch. I'm trying to get a t-shirt. Yeah, it's stupid. But the patch does fix a real problem found via various linters.

I've added both the hacktoberfest and hacktoberfest2021 tags to the project.
