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.
