Subject: include/denc: initialize local variable
X-Git-Tag: v18.0.0~195^2~6
X-Git-Url: http://git-server-git.apps.pok.os.sepia.ceph.com/?a=commitdiff_plain;h=fc9fe88eceb380ffaf498ade76c3a6a3769d3c9b;p=ceph-ci.git

include/denc: initialize local variable

to silence warning like:

../src/include/denc.h:834:27: warning: variable 'len' is uninitialized when used here [-Wuninitialized]
    v.push_back(p.get_ptr(len));
                          ^~~
