[ Upstream commit efab13e7d13a641a22c7508cde6e1a5285161944 ]
The IRQF_NO_AUTOEN can be used for the drivers that don't want interrupts to be enabled automatically via devm_request_threaded_irq(). Using this flag can provide be more robust compared to the way of calling disable_irq() after devm_request_threaded_irq() without the IRQF_NO_AUTOEN flag.
