Subject: arc: fix use of uninitialized arc_pmu
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=7002f77541f877a5590615ceb3da32b114f14b62;p=openwrt%2Fstaging%2Fblogic.git

arc: fix use of uninitialized arc_pmu

static arc_pmu in the arch/arc/kernel/perf_event.c is not initialized as
it's shadowed by a local variable of the same name in the
arc_pmu_device_probe.
