platform/mellanox: mlxreg-hotplug: Revert "move to use request_irq by IRQF_NO_AUTOEN flag"
It causes mlxreg-hotplug probing failure: request_threaded_irq() returns -EINVAL due to true value of condition: ((irqflags & IRQF_SHARED) && (irqflags & IRQF_NO_AUTOEN)) after flag "IRQF_NO_AUTOEN" has been added to: err = devm_request_irq(&pdev->dev, priv->irq, mlxreg_hotplug_irq_handler, IRQF_TRIGGER_FALLING | IRQF_SHARED | IRQF_NO_AUTOEN, "mlxreg-hotplug", priv); This reverts commit bee3ecfed0fc ("platform/mellanox: mlxreg-hotplug: move to use request_irq by IRQF_NO_AUTOEN flag").
