USB_AUTOPM_PUT_INTER(9) USB Core APIs USB_AUTOPM_PUT_INTER(9) NAME usb_autopm_put_interface_async - decrement a USB interface´s PM-usage counter SYNOPSIS void usb_autopm_put_interface_async(struct usb_interface * intf); ARGUMENTS intf the usb_interface whose counter should be decremented DESCRIPTION This routine does essentially the same thing as usb_autopm_put_interface: it decrements intf´s usage counter and queues a delayed autosuspend request if the counter is <= 0. The difference is that it does not acquire the device´s pm_mutex; callers must handle all synchronization issues themselves. Typically a driver would call this routine during an URB´s completion handler, if no more URBs were pending. This routine can run in atomic context. COPYRIGHT Kernel Hackers Manual 2.6.
