Subject: [PATCH] USB: FHCI: Correct the size argument to kzalloc
urb_priv->tds has type struct td **, not struct td *, so the
elements of the array should have pointer type, not structure type.
Convert kzalloc to kcalloc as well.
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>
