drivers/net/wan/dscc4.c: fix error return code
Move up the initialization of rc so that failure of pci_alloc_consistent returns -ENOMEM as well. A simplified version of the semantic match that finds this problem is as follows: (http://coccinelle.lip6.fr/) // <smpl> @@ identifier ret; expression e1,e2; @@ if (ret < 0) { ... return ret; } ... when != ret = e1 when forall *if(...) { ... when != ret = e2 * return ret; } // </smpl> Signed-off-by: Julia Lawall <Julia.Lawall@lip6.fr> Signed-off-by: David S. Miller <davem@davemloft.net>
