net/netlabel: Add kmalloc NULL tests
The test on map4 should be a test on map6. The semantic match that finds this problem is as follows: (http://www.emn.fr/x-info/coccinelle/) // <smpl> @@ expression *x; identifier f; constant char *C; @@ x = \(kmalloc\|kcalloc\|kzalloc\)(...); ... when != x == NULL when != x != NULL when != (x || ...) ( kfree(x) | f(...,C,...,x,...) | *f(...,x,...) | *x->f ) // </smpl> Signed-off-by: Julia Lawall <julia@diku.dk> Acked-by: Paul Moore <paul.moore@hp.com> Signed-off-by: David S. Miller <davem@davemloft.net>
