Re: [PATCH] driver base: slience unused warning

[Dan Carpenter]

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.
