[ Upstream commit d108370c644b153382632b3e5511ade575c91c86 ]
clang static analysis reports this representative problem:
label.c:1463:16: warning: Assigned value is garbage or undefined
label->hname = name;
^ ~~~~
In aa_update_label_name(), this the problem block of code
if (aa_label_acntsxprint(&name, ...) == -1)
return res;
On failure, aa_label_acntsxprint() has a more complicated return
that just -1. So check for a negative return.
It was also noted that the aa_label_acntsxprint() main comment refers
to a nonexistent parameter, so clean up the comment.
