Subject: ccanlint: remove empty statement warnings.
X-Git-Url: http://git.ozlabs.org/?p=ccan;a=commitdiff_plain;h=dfafd0a1f522277c9be5fc589885db38f706d108;hp=89fcdf8c701183e56d370876ec16a04ebbf921fb

ccanlint: remove empty statement warnings.

Since doesnt_matter() expands to nothing, GCC -Wextra suggests { }.
