drivers/net: Move a dereference below a NULL test
If the NULL test is necessary, then the dereference should be moved below the NULL test. The semantic patch that makes this change is as follows: (http://www.emn.fr/x-info/coccinelle/) // <smpl> @@ type T; expression E,E1; identifier i,fld; statement S; @@ - T i = E->fld; + T i; ... when != E=E1 when != i if (E == NULL||...) S + i = E->fld; // </smpl> Signed-off-by: Julia Lawall <julia@diku.dk> Signed-off-by: David S. Miller <davem@davemloft.net>
