Subject: [PATCH 1/2] arm_pmu: move to use request_irq by IRQF_NO_AUTOEN flag
Date: Wed, 2 Jun 2021 09:00:41 +0800 [thread overview]
Message-ID: <1622595642-61678-2-git-send-email-tiantao6@hisilicon.com> (raw)
In-Reply-To: <1622595642-61678-1-git-send-email-tiantao6@hisilicon.com>
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/
