From: Julia Lawall <[email protected]> In each case, 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; identifier i,fld; statement S; @@ - T i = E->fld; + T i; ... when != E when != i if (E == NULL) S + i = E->fld; // </smpl> Signed-off-by: Julia Lawall <[email protected]> --- drivers/infiniband/hw/nes/nes_cm.c | 3 ++- 1 files changed, 2 insertions(+), 1 deletions(-) diff --git a/drivers/infiniband/hw/nes/nes_cm.c b/drivers/infiniband/hw/nes/nes_cm.c index 2caf9da..2194ee2 100644 --- a/drivers/infiniband/hw/nes/nes_cm.c +++ b/drivers/infiniband/hw/nes/nes_cm.c @@ -376,13 +376,14 @@ int schedule_nes_timer(struct nes_cm_node *cm_node, struct sk_buff *skb, int close_when_complete) { unsigned long flags; - struct nes_cm_core *cm_core = cm_node->cm_core; + struct nes_cm_core *cm_core; struct nes_timer_entry *new_send; int ret = 0; u32 was_timer_set; if (!cm_node) return -EINVAL; + cm_core = cm_node->cm_core; new_send = kzalloc(sizeof(*new_send), GFP_ATOMIC); if (!new_send) return -1; _______________________________________________ general mailing list [email protected] http://lists.openfabrics.org/cgi-bin/mailman/listinfo/general To unsubscribe, please visit http://openib.org/mailman/listinfo/openib-general
