If the return values can be safely ignored the functions should be
updated to return void, if the functions are returning a value it is
sensible defensive programming to check it.

This is in no way a bug fix, please don't include noise like this - it
causes people to waste time doing things like considering it for backport.

Please submit patches using subject lines reflecting the style for the
subsystem, this makes it easier for people to identify relevant patches.
Look at what existing commits in the area you're changing are doing and
make sure your subject lines visually resemble what they're doing.
There's no need to resubmit to fix this alone.
