From: Julia Lawall <julia@xxxxxxx> list_for_each_entry binds its first argument to a non-null value, and thus any null test on the value of that argument is superfluous. The semantic patch that makes this change is as follows: (http://coccinelle.lip6.fr/) // <smpl> @@ iterator I; expression x; statement S,S1,S2; @@ I(x,...) { <... - if (x == NULL && ...) S ...> } // </smpl> Signed-off-by: Julia Lawall <julia@xxxxxxx> --- drivers/infiniband/hw/ehca/ehca_mrmw.c | 5 ----- 1 file changed, 5 deletions(-) diff --git a/drivers/infiniband/hw/ehca/ehca_mrmw.c b/drivers/infiniband/hw/ehca/ehca_mrmw.c index 31a68b9..53f4cd4 100644 --- a/drivers/infiniband/hw/ehca/ehca_mrmw.c +++ b/drivers/infiniband/hw/ehca/ehca_mrmw.c @@ -933,11 +933,6 @@ int ehca_unmap_fmr(struct list_head *fmr_list) /* check all FMR belong to same SHCA, and check internal flag */ list_for_each_entry(ib_fmr, fmr_list, list) { prev_shca = shca; - if (!ib_fmr) { - ehca_gen_err("bad fmr=%p in list", ib_fmr); - ret = -EINVAL; - goto unmap_fmr_exit0; - } shca = container_of(ib_fmr->device, struct ehca_shca, ib_device); e_fmr = container_of(ib_fmr, struct ehca_mr, ib.ib_fmr); -- To unsubscribe from this list: send the line "unsubscribe kernel-janitors" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
