X-Git-Url: http://git.cdn.openwrt.org/?a=commitdiff_plain;h=a63273d4992603979ddb181b6a8f07082839b39f;p=openwrt%2Fstaging%2Fblogic.git

RDS: Clear up some confusing code in send_remove_from_sock

The previous code was correct, but made the assumption that
if r_notifier was non-NULL then either r_recverr or r_notify
was true. Valid, but fragile. Changed to explicitly check
r_recverr (shows up in greps for recverr now, too.)
