snd_usb_endpoint_free

[Julia Lawall <julia.lawall@lip6.fr>]

The function snd_usb_endpoint_free in sound/usb/endpoint.c is defined as 
follows:

void snd_usb_endpoint_free(struct list_head *head)
{
        struct snd_usb_endpoint *ep;

        ep = list_entry(head, struct snd_usb_endpoint, list);
        release_urbs(ep, 1);
        kfree(ep);
}

I wonder if the final kfree should be list_del?  In practice, this 
function is only used from snd_usb_audio_disconnect in sound/usb/card.c 
where the entire list is destroyed, but it seems like quite a generic 
function that someone may someday want to use for just freeing one entry.
