Subject: pbrd: initialize structs used in hash_lookup
X-Git-Url: https://git.puffer.fish/?a=commitdiff_plain;h=54d4153afa6cedc895e0527e9afce0be27a109a4;p=matthieu%2Ffrr.git

pbrd: initialize structs used in hash_lookup

Doesn't seem to break anything but really poor style to pass potentially
uninitialized data to hash_lookup.
