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>
As with patch 1, I see that the patch above was merged in v5.13-rc1 as commit:

  cbe16f35bee6880b ("genirq: Add IRQF_NO_AUTOEN for request_irq/nmi()")

With that in mind:

Acked-by: Mark Rutland <mark.rutland@arm.com>

I expect Will will pick this up.

Thanks,
Mark.
