From 8fe392b8fdb93ced86e1661bff91af95ee234cf9 Mon Sep 17 00:00:00 2001 From: Ezequiel Garcia Date: Tue, 23 Oct 2012 15:57:06 -0300 Subject: [PATCH] [media] usbvision: 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/usbvision/usbvision-i2c.c | 3 +-- 1 file changed, 1 insertion(+), 2 deletions(-) diff --git a/drivers/media/usb/usbvision/usbvision-i2c.c b/drivers/media/usb/usbvision/usbvision-i2c.c index 89fec029e924..ba262a32bd3a 100644 --- a/drivers/media/usb/usbvision/usbvision-i2c.c +++ b/drivers/media/usb/usbvision/usbvision-i2c.c @@ -189,8 +189,7 @@ int usbvision_i2c_register(struct usb_usbvision *usbvision) if (usbvision->registered_i2c) return 0; - memcpy(&usbvision->i2c_adap, &i2c_adap_template, - sizeof(struct i2c_adapter)); + usbvision->i2c_adap = i2c_adap_template; sprintf(usbvision->i2c_adap.name, "%s-%d-%s", i2c_adap_template.name, usbvision->dev->bus->busnum, usbvision->dev->devpath); -- 2.30.2
