This rule finds comparisons of a pointer to null that occur after a reference of that pointer. It's likely either the check is not required and can be removed, or it should be moved to before the dereference so that a null pointer dereference does not occur.

The check should be moved to before the dereference, in a way that prevents a null pointer value from being dereferenced. If it's clear that the pointer cannot be null, consider removing the check instead.
