From 228bae05be328045e6dfb4d3bf2600e6547c1d13 Mon Sep 17 00:00:00 2001 From: Karsten Graul Date: Fri, 12 Apr 2019 12:57:28 +0200 Subject: net/smc: code cleanup smc_listen_work In smc_listen_work() the variables rc and reason_code are defined which have the same meaning. Eliminate reason_code in favor of the shorter name rc. No functional changes. Rename the functions smc_check_ism() and smc_check_rdma() into smc_find_ism_device() and smc_find_rdma_device() to make there purpose more clear. No functional changes.
