Subject: Add ATTR_UNUSED to HT_FIND
X-Git-Tag: tor-0.2.5.5-alpha~9
X-Git-Url: http://git.ipfire.org/gitweb.cgi?a=commitdiff_plain;h=9b10d7a7dd822af0584474285d00c8228fbdbb82;p=thirdparty%2Ftor.git

Add ATTR_UNUSED to HT_FIND

The fix for bug 8746 added a hashtable instance that never actually
invoked HT_FIND.  This caused a warning, since we didn't mark HT_FIND
as okay-not-to-use.
