If we want to further simplify, I don't see any need for having 'ret'
either and to just call the methods in check():

    check(add_decoration(&vars->n, vars->two, NULL), ==, NULL);

which would also provide more context in the stdout rather than printing
'check(ret == NULL)'. But, I believe you would have already considered
that but kept 'ret' in favor of code readability, so I am also fine with
it. Thanks for patch.

Good idea!  Worth a separate patch, though.
