Subject: RDMA/addr: Fix return of uninitialized ret value
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=1bdd6384c2b43cac9be8d6f2c298bcf39f50cd07;p=linux-beck.git

RDMA/addr: Fix return of uninitialized ret value

Commit b23dd4fe42b4 ("ipv4: Make output route lookup return rtable
directly") resulted in leaving ret uninitialized, where it may later
be returned.
