The problem here is the missing empty line, not that 'int err = <something>;' part.
So just add the empty line and don't split up the variable assignment.

Why remove this empty line? It has nothing to do with what you are trying
to fix.

And I am sure this never produced a cppcheck warning since there is an
empty line. If cppcheck DOES produce a warning on this, then it is a
useless application.

Honestly, none of these changes are worth the effort, so I just reject this.
