| |
From: Julia Lawall <julia@diku.dk>
sizeof(dev->dev_addr) is the size of a pointer. A few lines above, the size of this field is obtained using netdev->addr_len for a call to memcpy, so do the same here.
A simplified version of the semantic patch that finds this problem is as follows: (http://coccinelle.lip6.fr/)
// <smpl> @@ expression *x; expression f; type T; @@
*f(...,(T)x,...) // </smpl>
