Applied.

However, I would *really* ask you to avoid that kind of subjects in
the future.  Proper subject for that one is "NULL noise in <file>" (or
<file>:<function>.  Sparse doesn't even need to be mentioned.

sparse generates many kinds of warnings.  And they are neither equal
nor equally interesting.

Kindly use subjects that would tell what's going on; "$TOOL gives
some warning in $FILE" is bloody useless.
