From 968bfb566dd193f912ccab47aaa50f3112f6f82d Mon Sep 17 00:00:00 2001 From: Heiko Carstens Date: Mon, 6 May 2024 21:44:51 +0200 Subject: s390/netiucv: Make use of iucv_alloc_device() Make use of iucv_alloc_device() to get rid of quite some code. In addition this also removes a cast to an incompatible function (clang W=1): drivers/s390/net/netiucv.c:1716:18: error: cast from 'void (*)(const void *)' to 'void (*)(struct device *)' converts to incompatible function type [-Werror,-Wcast-function-type-strict] 1716 | dev->release = (void (*)(struct device *))kfree; | ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Reported-by: Nathan Chancellor Closes: https://lore.kernel.org/r/20240417-s390-drivers-fix-cast-function-type-v1-3-fd048c9903b0@kernel.org Acked-by: Alexandra Winter Link: https://lore.kernel.org/r/20240506194454.1160315-4-hca@linux.ibm.com Signed-off-by: Heiko Carstens Signed-off-by: Alexander Gordeev --- drivers/s390/net/netiucv.c | 20 ++++---------------- 1 file changed, 4 insertions(+), 16 deletions(-) (limited to 'drivers/s390') diff --git a/drivers/s390/net/netiucv.c b/drivers/s390/net/netiucv.c index 8852b03f943b..039e18d46f76 100644 --- a/drivers/s390/net/netiucv.c +++ b/drivers/s390/net/netiucv.c @@ -1696,26 +1696,14 @@ static const struct attribute_group *netiucv_attr_groups[] = { static int netiucv_register_device(struct net_device *ndev) { struct netiucv_priv *priv = netdev_priv(ndev); - struct device *dev = kzalloc(sizeof(struct device), GFP_KERNEL); + struct device *dev; int ret; IUCV_DBF_TEXT(trace, 3, __func__); - if (dev) { - dev_set_name(dev, "net%s", ndev->name); - dev->bus = &iucv_bus; - dev->parent = iucv_root; - dev->groups = netiucv_attr_groups; - /* - * The release function could be called after the - * module has been unloaded.
