From: "Lad, Prabhakar" <[email protected]> this patch fixes following sparse warning: net/core/dev.c: In function 'validate_xmit_skb_list': net/core/dev.c:2720: warning: 'tail' may be used uninitialized in this function
Although its a false positive, as head is assigned to NULL in the beginning, due which later in the loop tail is assigned to skb->prev.
