Coccinelle: noderef: Add new rules and correct the old rule
Add new rules to detect the cases where sizeof is used in function calls as a argument. Also, for the patch mode third rule should behave same as second rule with arguments reversed. So, change that as well. Signed-off-by: Vaishali Thakkar <vaishali.thakkar@oracle.com> Acked-by: Julia Lawall <julia.lawall@lip6.fr> Signed-off-by: Michal Marek <mmarek@suse.com>
