usb_autopm_put_interface - decrement a USB interfaceAqs PM-usage counter
2. SYNOPSIS ▲
void usb_autopm_put_interface(struct usb_interface * intf );
3. ARGUMENTS ▲
the usb_interface whose counter should be decremented
4. DESCRIPTION ▲
This routine should be called by an interface driver when it is finished using intf and wants to allow it to autosuspend. A typical example would be a character-device driver when its device file is closed.
The routine decrements intfAqs usage counter. When the counter reaches 0, a delayed autosuspend request for intfAqs device is attempted. The attempt may fail (see autosuspend_check).
This routine can run only in process context.
