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: Hans de Goede <hdego...@redhat.com> Signed-off-by: Peter Senna Tschudin <peter.se...@gmail.com> Signed-off-by: Ezequiel Garcia <elezegar...@gmail.com> --- drivers/media/usb/pwc/pwc-if.c | 2 +- 1 files changed, 1 insertions(+), 1 deletions(-) diff --git a/drivers/media/usb/pwc/pwc-if.c b/drivers/media/usb/pwc/pwc-if.c index 42e36ba..cc5c7d8 100644 --- a/drivers/media/usb/pwc/pwc-if.c +++ b/drivers/media/usb/pwc/pwc-if.c @@ -1003,7 +1003,7 @@ static int usb_pwc_probe(struct usb_interface *intf, const struct usb_device_id vb2_queue_init(&pdev->vb_queue); /* Init video_device structure */ - memcpy(&pdev->vdev, &pwc_template, sizeof(pwc_template)); + pdev->vdev = pwc_template; strcpy(pdev->vdev.name, name); pdev->vdev.queue = &pdev->vb_queue; pdev->vdev.queue->lock = &pdev->vb_queue_lock; -- 1.7.4.4 -- To unsubscribe from this list: send the line "unsubscribe linux-media" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
