mmc: vub300: add missing usb_free_urb
Add missing usb_free_urb on failure path after usb_alloc_urb.
A simplified version of the semantic match that finds this problem is as
follows: (http://coccinelle.lip6.fr/)
// <smpl>
@km exists@
local idexpression e;
expression e1,e2,e3;
type T,T1;
identifier f;
@@
* e = usb_alloc_urb(...)
... when any
when != e = e1
when != e1 = (T)e
when != e1(...,(T)e,...)
when != &e->f
if(...) { ... when != e2(...,(T1)e,...)
when != e3 = e
when forall
(
return <+...e...+>;
|
* return ...;
) }
// </smpl>
