Hello, Sorry for the just sent unfinished mail. I pressed "send" instead of "reedit" after adding tglx to the recipients. Apart from the topic handled in this mail it's complete though.

The use case is that when probing an uart driver the modem control irqs should only be enabled when the enable_ms callback is called by the tty/serial framework. So we'd like to have something like request_irq_noenable. This way the enable_ms callback would just need to call enable_irq without first checking if the handler is already setup. The less nice alternatives are: - use request_irq(..); disable_irq(); and handle the short window where irqs are on but not yet desired. - only request_irq in the enable_ms callback, and free_irq in disable_ms. Any ideas?
