The semantic patch that showed this suggestion is kzalloc.cocci Signed-off-by: Iulia Manda Signed-off-by: Greg Kroah-Hartman --- diff --git a/drivers/staging/vt6656/iwctl.c b/drivers/staging/vt6656/iwctl.c index 60264a655f24..bedc8104e835 100644 --- a/drivers/staging/vt6656/iwctl.c +++ b/drivers/staging/vt6656/iwctl.c @@ -725,10 +725,10 @@ int iwctl_giwaplist(struct net_device *dev, struct iw_request_info *info, if (!wrq->pointer) return -EINVAL; - sock = kzalloc(sizeof(struct sockaddr) * IW_MAX_AP, GFP_KERNEL); + sock = kcalloc(IW_MAX_AP, sizeof(struct sockaddr), GFP_KERNEL); if (sock == NULL) return -ENOMEM; - qual = kzalloc(sizeof(struct iw_quality) * IW_MAX_AP, GFP_KERNEL); + qual = kcalloc(IW_MAX_AP, sizeof(struct iw_quality), GFP_KERNEL); if (qual == NULL) { kfree(sock); return -ENOMEM;
