Subject: nl80211: Fix tx_control_port error print
X-Git-Tag: hostap_2_10~1647
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=17ba51b14dc19c0e1ec86888ff6a010479c25fdf;p=thirdparty%2Fhostap.git

nl80211: Fix tx_control_port error print

send_and_recv_msgs() returns a negative number as the error code and
that needs to be negated for strerror().
