USB_AUTOPM_PUT_INTER(9) USB Core APIs USB_AUTOPM_PUT_INTER(9)
NAME
usb_autopm_put_interface - decrement a USB interface's PM-usage counter
SYNOPSIS
void usb_autopm_put_interface(struct usb_interface * intf);
ARGUMENTS
intf
the usb_interface whose counter should be decremented
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 intf's usage counter. When the counter reaches
0, a delayed autosuspend request for intf's device is attempted. The
attempt may fail (see autosuspend_check).
This routine can run only in process context.
