Subject: Update zstd_lazy.c
X-Git-Tag: v1.5.1~1^2~169^2
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=refs%2Fpull%2F2653%2Fhead;p=thirdparty%2Fzstd.git

Update zstd_lazy.c

It put the changes back when I tried to make a separate pull request, i don't understand githubs interface at all.
