SCSI: aacraid: Eliminate use after free
commit 8a52da632ceb9d8b776494563df579e87b7b586b upstream.
The debugging code using the freed structure is moved before the kfree.
A simplified version of the semantic match that finds this problem is as
follows: (http://coccinelle.lip6.fr/)
// <smpl>
@free@
expression E;
position p;
@@
kfree@p(E)
@@
expression free.E, subE<=free.E, E1;
position free.p;
@@
kfree@p(E)
...
(
subE = E1
|
* E
)
// </smpl>
