NAME¶
usb_autopm_set_interface - set a USB interface´s autosuspend state
SYNOPSIS¶
int usb_autopm_set_interface(struct usb_interface * intf);
ARGUMENTS¶
intf
the usb_interface whose state should be set
DESCRIPTION¶
This routine sets the autosuspend state of intf´s device according to intf´s usage counter, which the caller must have set previously. If the counter is <= 0, the device is autosuspended (if it isn´t already suspended and if nothing else prevents the autosuspend). If the counter is > 0, the device is autoresumed (if it isn´t already awake).
