From 5c2edefed74fb29b35634bce1b4c38ce1fdb2ce6 Mon Sep 17 00:00:00 2001 From: Ezequiel Garcia Date: Tue, 23 Oct 2012 15:57:08 -0300 Subject: [media] pwc: Replace memcpy with struct assignment 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/) // @@ identifier struct_name; struct struct_name to; struct struct_name from; expression E; @@ -memcpy(&(to), &(from), E); +to = from; // Signed-off-by: Peter Senna Tschudin Signed-off-by: Ezequiel Garcia Signed-off-by: Mauro Carvalho Chehab --- drivers/media/usb/pwc/pwc-if.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) (limited to 'drivers/media/usb/pwc/pwc-if.c') diff --git a/drivers/media/usb/pwc/pwc-if.c b/drivers/media/usb/pwc/pwc-if.c index 21c15233c6ae..5ec15cb1ed26 100644 --- a/drivers/media/usb/pwc/pwc-if.c +++ b/drivers/media/usb/pwc/pwc-if.c @@ -1008,7 +1008,7 @@ static int usb_pwc_probe(struct usb_interface *intf, const struct usb_device_id } /* 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; -- cgit v1.2.1
