From 9e89fd8b7db71038fd9f70f34e210963fa8fc980 Mon Sep 17 00:00:00 2001 From: Sven Wegener Date: Thu, 29 May 2014 20:27:06 +0000 Subject: ipv6: Shrink udp_v6_mcast_next() to one socket variable To avoid the confusion of having two variables, shrink the function to only use the parameter variable for looping.
