Subject: Re: USB remote wakeup through gpio interrupt

Hi Peter,

Thanks for your reply.

I can use pm_runtime_get in interrupt handler, but i am not getting
your idea of using pm_runtime_put in interrupt handler?

My device is usb telephony modem, which will give interrupt through
gpio when call comes. so at that time i want to wakeup the usb
functionality as remote wakeup is not working properly.

will pm_runtime_put suspend the device immidiately or it will not
suspend the device till it is in use?

thanks,
jagdish gediya
