[PATCH fixes] MIPS: perf: Fix build with CONFIG_CPU_BMIPS5000 enabled

From: Florian Fainelli
Date: Tue Mar 26 2019 - 13:03:59 EST


The 'event' variable may be unused in case only CONFIG_CPU_BMIPS5000
being enabled:

arch/mips/kernel/perf_event_mipsxx.c: In function 'mipsxx_pmu_enable_event':
arch/mips/kernel/perf_event_mipsxx.c:326:21: error: unused variable 'event' [-Werror=unused-variable]
struct perf_event *event = container_of(evt, struct perf_event, hw);
^~~~~
