Subject: rpc: remove unneeded variable 'ret' in rdma_listen_handler
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=ac5bb5b3b0502b90b489e6b19c46b8c3dbe2e640;p=openwrt%2Fstaging%2Fblogic.git

rpc: remove unneeded variable 'ret' in rdma_listen_handler

The ret is not modified after initalization, So just remove the variable
and return 0.
