NAME
       usb_autopm_get_interface_async - increment a USB interface´s PM-usage
       counter

SYNOPSIS
       int usb_autopm_get_interface_async(struct usb_interface * intf);

ARGUMENTS
       intf
	   the usb_interface whose counter should be incremented

DESCRIPTION
       This routine does much the same thing as usb_autopm_get_interface: it
       increments intf´s usage counter and queues an autoresume request if the
       result is > 0. The differences are that it does not acquire the
       device´s pm_mutex (callers must handle all synchronization issues
       themselves), and it does not autoresume the device directly (it only
       queues a request). After a successful call, the device will generally
       not yet be resumed.

       This routine can run in atomic context.
