usb: gadget: Use kcalloc instead of kzalloc to allocate array
The advantage of kcalloc is, that will prevent integer overflows which could result from the multiplication of number of elements and size and it is also a bit nicer to read. The semantic patch that makes this change is available in https://lkml.org/lkml/2011/11/25/107 Signed-off-by: Thomas Meyer <thomas@m3y3r.de> Acked-by: Michal Nazarewicz <[4]mina86@mina86.com> Signed-off-by: Felipe Balbi <balbi@ti.com>
