This kind of memcpy() is error-prone. Its replacement with a struct assignment is prefered because it's type-safe and much easier to read. Found by coccinelle. Hand patched and reviewed. Tested by compilation only. A simplified version of the semantic match that finds this problem is as follows: (http://coccinelle.lip6.fr/) // <smpl> @@ identifier struct_name; struct struct_name to; struct struct_name from; expression E; @@ -memcpy(&(to), &(from), E); +to = from; // </smpl> Cc: Mike Isely <isely@xxxxxxxxx> Signed-off-by: Peter Senna Tschudin <peter.senna@xxxxxxxxx> Signed-off-by: Ezequiel Garcia <elezegarcia@xxxxxxxxx> --- drivers/media/usb/hdpvr/hdpvr-i2c.c | 3 +-- 1 files changed, 1 insertions(+), 2 deletions(-) diff --git a/drivers/media/usb/hdpvr/hdpvr-i2c.c b/drivers/media/usb/hdpvr/hdpvr-i2c.c index 82e819f..2df60bf 100644 --- a/drivers/media/usb/hdpvr/hdpvr-i2c.c +++ b/drivers/media/usb/hdpvr/hdpvr-i2c.c @@ -217,8 +217,7 @@ int hdpvr_register_i2c_adapter(struct hdpvr_device *dev) hdpvr_activate_ir(dev); - memcpy(&dev->i2c_adapter, &hdpvr_i2c_adapter_template, - sizeof(struct i2c_adapter)); + dev->i2c_adapter = hdpvr_i2c_adapter_template; dev->i2c_adapter.dev.parent = &dev->udev->dev; i2c_set_adapdata(&dev->i2c_adapter, dev); -- 1.7.4.4 -- 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
