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.Lawall@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(-)
