Subject[PATCH 3/5] drivers/scsi : Correct the size argument to kmalloc
From: Julia Lawall <julia@diku.dk>

In each case, the destination of the allocation has type struct **, so the
elements of the array should have pointer type, not structure type.

The semantic patch that makes this change is as follows:
(http://coccinelle.lip6.fr/)

// <smpl>
@disable sizeof_type_expr@
type T;
T **x;
@@

x =
<+...sizeof(
- T
+ *x
)...+>
// </smpl>

Signed-off-by: Julia Lawall <julia@diku.dk>
