## 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 much the same thing as `usb_autopm_put_interface`: It decrements `intf`'s usage counter and schedules a delayed autosuspend request if the counter is <= 0. The difference is that it does not perform any synchronization; callers should hold a private lock and 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.
