NAME

6       usb_autopm_put_interface - decrement a USB interface's PM-usage counter
7

SYNOPSIS

9       void usb_autopm_put_interface(struct usb_interface * intf);
10

ARGUMENTS

12       intf
13           the usb_interface whose counter should be decremented
14

DESCRIPTION

16       This routine should be called by an interface driver when it is
17       finished using intf and wants to allow it to autosuspend. A typical
18       example would be a character-device driver when its device file is
19       closed.
20
21       The routine decrements intf's usage counter. When the counter reaches
22       0, a delayed autosuspend request for intf's device is attempted. The
23       attempt may fail (see autosuspend_check).
24
25       This routine can run only in process context.
