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").
