Subject: [PATCH v2] arm: kernel/perf_event_cpu.c: remove unnecessary null pointer dereference check

From: [email-masked] (Cong Ding)
Date: Mon, 14 Jan 2013 17:40:55 +0000

The NULL pointer check is not necessary.  cpu_pmu_init() is called
after cpu_pmu has already been dereferenced by its caller:

	cpu_pmu = pmu;
	cpu_pmu->plat_device = pdev;
	cpu_pmu_init(cpu_pmu);
