knav_queue_open always returns an ERR_PTR value, never NULL. This can be confirmed by unfolding the function calls and conforms to the function's documentation. Thus, replace IS_ERR_OR_NULL by IS_ERR in error checks.
The change is made using the following semantic patch: (http://coccinelle.lip6.fr/) // <smpl> @@ expression x; statement S; @@ x = knav_queue_open(...); if ( - IS_ERR_OR_NULL + IS_ERR (x)) S // </smpl> Signed-off-by: Julia Lawall <julia.law...@lip6.fr> --- The patches in this series are completely independent of each other, except for having been made from the same specification. drivers/net/ethernet/ti/netcp_core.c | 6 +++--- 1 file changed, 3 insertions(+), 3 deletions(-) diff --git a/drivers/net/ethernet/ti/netcp_core.c b/drivers/net/ethernet/ti/netcp_core.c index 78b4c83..7981b99 100644 --- a/drivers/net/ethernet/ti/netcp_core.c +++ b/drivers/net/ethernet/ti/netcp_core.c @@ -1568,7 +1568,7 @@ static int netcp_setup_navigator_resources(struct net_device *ndev) /* open Tx completion queue */ snprintf(name, sizeof(name), "tx-compl-%s", ndev->name); netcp->tx_compl_q = knav_queue_open(name, netcp->tx_compl_qid, 0); - if (IS_ERR_OR_NULL(netcp->tx_compl_q)) { + if (IS_ERR(netcp->tx_compl_q)) { ret = PTR_ERR(netcp->tx_compl_q); goto fail; } @@ -1588,7 +1588,7 @@ static int netcp_setup_navigator_resources(struct net_device *ndev) /* open Rx completion queue */ snprintf(name, sizeof(name), "rx-compl-%s", ndev->name); netcp->rx_queue = knav_queue_open(name, netcp->rx_queue_id, 0); - if (IS_ERR_OR_NULL(netcp->rx_queue)) { + if (IS_ERR(netcp->rx_queue)) { ret = PTR_ERR(netcp->rx_queue); goto fail; } @@ -1610,7 +1610,7 @@ static int netcp_setup_navigator_resources(struct net_device *ndev) ++i) { snprintf(name, sizeof(name), "rx-fdq-%s-%d", ndev->name, i); netcp->rx_fdq[i] = knav_queue_open(name, KNAV_QUEUE_GP, 0); - if (IS_ERR_OR_NULL(netcp->rx_fdq[i])) { + if (IS_ERR(netcp->rx_fdq[i])) { ret = PTR_ERR(netcp->rx_fdq[i]); goto fail; }
