This is a W=1 static checker warning. We've already reviewed it, and marked it as old. There isn't anything else required. Or are we close to promoting the unused-but-set-variable warning from W=1 to being on by default? How many of these warnings are remaining? It it's like only 20-50 warnings left then maybe we should consider the other options but that kind of information needs to be in the cover letter or otherwise we won't know about it. regards, dan carpenter
