usb_autopm_put_interface_async - decrement a USB interfaceAqs PM-usage counter
2. SYNOPSIS ▲
void usb_autopm_put_interface_async(struct usb_interface * intf );
3. ARGUMENTS ▲
the usb_interface whose counter should be decremented
4. DESCRIPTION ▲
This routine does much the same thing as usb_autopm_put_interface: It decrements intfAqs 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 URBAqs completion handler, if no more URBs were pending.
This routine can run in atomic context.
