usb: wusbcore: security: cast sizeof to int for comparison
Comparing an int to a size, which is unsigned, causes the int to become
unsigned, giving the wrong result. usb_get_descriptor can return a
negative error code.
A simplified version of the semantic match that finds this problem is as
follows: (http://coccinelle.lip6.fr/)
// <smpl>
@@
int x;
expression e,e1;
identifier f;
@@
*x = f(...);
... when != x = e1
when != if (x < 0 || ...) { ... return ...; }
*x < sizeof(e)
// </smpl>
