Subject: resolved: no need to store return value of dns_server_possible_features()
X-Git-Tag: v229~189^2~16
X-Git-Url: http://git.ipfire.org/gitweb.cgi?a=commitdiff_plain;h=0e4fb6b2dedf590741220b806c92e9e68857b457;p=thirdparty%2Fsystemd.git

resolved: no need to store return value of dns_server_possible_features()

The call already updates possible_features, it's pointless doing this in
the caller a second time.
