Subject: udptl: Ensure fec[] in udptl_build_packet() is initialized.
X-Git-Tag: 10.3.0~35
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=f892e9152d8cfbc4c60129620e789300cc06102b;p=thirdparty%2Fasterisk.git

udptl: Ensure fec[] in udptl_build_packet() is initialized.

Scan results indicated that this array could be used uninitialized.  At a quick
look, it looks correct.  In any case, initializing it is a Good Thing (tm).
