drivers/net: Correct NULL test
Test the value that was just allocated rather than the previously tested one. A simplified version of the semantic match that finds this problem is as follows: (http://coccinelle.lip6.fr/) // <smpl> @r@ expression *x; expression e; identifier l; @@ if (x == NULL || ...) { ... when forall return ...; } ... when != goto l; when != x = e when != &x *x == NULL // </smpl> Signed-off-by: Julia Lawall <julia@diku.dk> Signed-off-by: David S. Miller <davem@davemloft.net>
