A few nitpicks, otherwise it looks good,

You kept within 80c nearly everywhere, but there are a few calls where
you added 'NULL' that go over the 80c now. Not sure if that was
intended?!

This is not aligned with the opening bracket here and a few below. Maybe
you can fix it with your patch as well.

Here and below, the function call got shorter, please fix the
indentation in the following lines.
Best,
