Subject: [PATCH 2/5] powerpc/perf: Remove set but not used variable 'target'
Date: Tue, 19 Nov 2019 14:14:31 +0800 [thread overview]
Message-ID: <1574144074-142032-3-git-send-email-zhengbin13@huawei.com> (raw)
In-Reply-To: <1574144074-142032-1-git-send-email-zhengbin13@huawei.com>
Fixes gcc '-Wunused-but-set-variable' warning:
arch/powerpc/perf/imc-pmu.c: In function trace_imc_event_init:
arch/powerpc/perf/imc-pmu.c:1292:22: warning: variable target set but not used [-Wunused-but-set-variable]
It is introduced by commit 012ae244845f ("powerpc/perf:
Trace imc PMU functions"), but never used, so remove it.
