Subject: init_by_resolv_conf: fix compiler warnings
X-Git-Tag: upstream/1.10.0~220
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=bd6636c1387f4593f6df35297735a1632271da39;p=platform%2Fupstream%2Fc-ares.git

init_by_resolv_conf: fix compiler warnings

The code received the return codes in the 'status' variable without
using it. Instead we just ignore those particular errors.
