You're just assigning a return value so that the compiler can't tell if
we've missed anything, that's often a sign of just papering over the
cracks without understanding the problem - for example there may be a
missing else case in some error path that the compiler was trying to
tell you about where other cleanup is needed. The changelog should say
what the problem was and why the change solves it sensibly.
