Subject: util/qemu-sockets.c: Avoid unused variable warnings
X-Git-Tag: Tizen_Studio_1.3_Release_p2.3.2~629^2~25^2
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=378c2c2d99368977470b65be6d7aadf3b35e6e5d;p=sdk%2Femulator%2Fqemu.git

util/qemu-sockets.c: Avoid unused variable warnings

The 'on' variable is never used, and 'off' is only used
if IPV6_V6ONLY is defined; delete 'on' and move 'off' to
the point where it is used. This avoids warnings from
clang 3.4.
