Subject: ARC: perf: Remove unnecessary local variable
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=082ae1e1570c69a06221701718f548bd4000b95b;p=linux-beck.git

ARC: perf: Remove unnecessary local variable

Directly return the result of perf_pmu_register() in
arc_pmu_device_probe() instead of assigning and returning variable ret.
