This looks like a regression - it's better form to use the object name rather than the type of the object since this prevents errors if the type changes. What coccinelle was suggesting here was to replace with a simple assingment statement rather than change the argument within the memcpy(), I think this stops the warning showing because of that issue since it makes it harder for coccinelle to figure out that this is a memcpy() of the whole object.
