As commit cbe16f35bee6 ("genirq: Add IRQF_NO_AUTOEN for request_irq/nmi()")
said, reqeust_irq() and then disable_irq() is unsafe. In the small time gap
between request_irq() and disable_irq(), interrupts can still come.
IRQF_NO_AUTOEN flag can be used by drivers to request_irq(). It prevents
the automatic enabling of the requested interrupt in the same
safe way. With that the usage can be simplified and corrected.
Compile-tested only.
Changes in v2:
- Correct the commit subject.
- Add reviewed-by.
