Subject: [PATCH] drm/exynos: move to use request_irq by IRQF_NO_AUTOEN flag
Date: Fri, 12 Mar 2021 19:43:05 +0800	[thread overview]
Message-ID: <1615549385-33784-1-git-send-email-tiantao6@hisilicon.com> (raw)

After this patch cbe16f35bee68 genirq: Add IRQF_NO_AUTOEN for
request_irq/nmi() is merged. 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.
