Unfortunately, that's not true, at least with the Fedora Rawhide
version of sparse. From yesterday's build of next-20140403:

[/usr/src/linux-next] sparse --version
0.5.0
[/usr/src/linux-next] grep err.h build.default | sort | uniq -c
1491 include/linux/err.h:29:23: warning: dereference of noderef expression
2 include/linux/err.h:29:23: warning: too many warnings
2493 include/linux/err.h:34:16: warning: dereference of noderef expression
59 include/linux/err.h:39:17: warning: dereference of noderef expression
59 include/linux/err.h:39:24: warning: dereference of noderef expression
124 include/linux/err.h:52:25: warning: dereference of noderef expression
18 include/linux/err.h:57:20: warning: dereference of noderef expression
18 include/linux/err.h:58:32: warning: dereference of noderef expression

(Oddly enough, the tarball in the .src.rpm seems to match the one on kernel.org,
and nothing fishy in the .spec file, so I'm confused now...)
