The patch titled drivers/net/wireless/libertas: move a dereference below a NULL test has been removed from the -mm tree. Its filename was drivers-net-wireless-libertas-move-a-dereference-below-a-null-test.patch This patch was dropped because it was merged into mainline or a subsystem tree The current -mm tree may be found at http://userweb.kernel.org/~akpm/mmotm/ ------------------------------------------------------ Subject: drivers/net/wireless/libertas: move a dereference below a NULL test From: Julia Lawall <julia@xxxxxxx> In each case, if the NULL test is necessary, then the dereference should be moved below the NULL test. I have also taken advantage of the availability of the value of priv->dev in the subsequent calls to netif_stop_queue and netif_carrier_off. 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 <julia@xxxxxxx> Acked-by: Dan Williams <dcbw@xxxxxxxxxx> Signed-off-by: Andrew Morton <akpm@xxxxxxxxxxxxxxxxxxxx> --- drivers/net/wireless/libertas/main.c | 7 ++++--- 1 file changed, 4 insertions(+), 3 deletions(-) diff -puN drivers/net/wireless/libertas/main.c~drivers-net-wireless-libertas-move-a-dereference-below-a-null-test drivers/net/wireless/libertas/main.c --- a/drivers/net/wireless/libertas/main.c~drivers-net-wireless-libertas-move-a-dereference-below-a-null-test +++ a/drivers/net/wireless/libertas/main.c @@ -1369,7 +1369,7 @@ EXPORT_SYMBOL_GPL(lbs_start_card); void lbs_stop_card(struct lbs_private *priv) { - struct net_device *dev = priv->dev; + struct net_device *dev; struct cmd_ctrl_node *cmdnode; unsigned long flags; @@ -1377,9 +1377,10 @@ void lbs_stop_card(struct lbs_private *p if (!priv) goto out; + dev = priv->dev; - netif_stop_queue(priv->dev); - netif_carrier_off(priv->dev); + netif_stop_queue(dev); + netif_carrier_off(dev); lbs_debugfs_remove_one(priv); if (priv->mesh_tlv) { _ Patches currently in -mm which might be from julia@xxxxxxx are linux-next.patch -- To unsubscribe from this list: send the line "unsubscribe mm-commits" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
