X-Git-Tag: accepted/tizen/unified/20230118.172025~6433^2~50
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=3f22bb137eb03ab27eaaa8b40d3e072eb541444e;p=platform%2Fkernel%2Flinux-rpi.git

ipv6: change return type from int to void for mld_process_v2

The mld_process_v2 only returned 0.

So, the return type is changed to void.
