[NET] ppp: Remove unnecessary pskb_may_pull
In ppp_receive_nonmp_frame, we call pskb_may_pull(skb, skb->len) if the tailroom is >= 124. This is pointless because this pskb_may_pull is only needed if the skb is non-linear. However, if it is non-linear then the tailroom would be zero. So it can be safely removed. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au> Signed-off-by: David S. Miller <davem@davemloft.net>
