ataflop: adjust NULL test
dtp is derefenced on the lines above the test !dtp, and so it cannot be
NULL at this point.
A simplified version of the semantic match that finds this problem is as
follows: (http://www.emn.fr/x-info/coccinelle/)
// <smpl>
@r@
expression x,E,E1;
identifier f,l;
position p1,p2;
@@
*x@p1->f = E1;
... when != x = E
when != goto l;
(
*x@p2 == NULL
|
*x@p2 != NULL
)
// </smpl>
