Subject: [PATCH 1/2] drivers/perf: hisi: Remove redundant initialized of pmu->name
Date: Mon, 3 Apr 2023 16:14:22 +0800	[thread overview]
Message-ID: <20230403081423.62460-2-hejunhao3@huawei.com> (raw)
In-Reply-To: <20230403081423.62460-1-hejunhao3@huawei.com>

"pmu->name" is initialized by perf_pmu_register() function, so remove
the redundant initialized in hisi_pmu_init().
