From 3a5a89d30ee3d5d8b55490e3c63bf533b196e1c8 Mon Sep 17 00:00:00 2001 From: Mark Rutland Date: Tue, 11 Apr 2017 09:39:48 +0100 Subject: drivers/perf: arm_pmu: simplify cpu_pmu_request_irqs() The ARM PMU framework code always uses armpmu_dispatch_irq as its common IRQ handler. Passing this down from cpu_pmu_init() is somewhat pointless, and gets in the way of refactoring. This patch makes cpu_pmu_request_irqs() always use armpmu_dispatch_irq as the handler when requesting IRQs, and removes the handler parameter from its prototype.
