arm_pmu: move to use request_irq by IRQF_NO_AUTOEN flag
request_irq() after setting IRQ_NOAUTOEN as below irq_set_status_flags(irq, IRQ_NOAUTOEN); request_irq(dev, irq...); can be replaced by request_irq() with IRQF_NO_AUTOEN flag. this patch is made base on "add IRQF_NO_AUTOEN for request_irq" which is being merged: https://lore.kernel.org/patchwork/patch/1388765/ Signed-off-by: Tian Tao <tiantao6@hisilicon.com> Acked-by: Mark Rutland <mark.rutland@arm.com> Link: https://lore.kernel.org/r/1622595642-61678-2-git-send-email-tiantao6@hisilicon.com Signed-off-by: Will Deacon <will@kernel.org>
