2011-12-09usb: gadget: renesas_usbhs: Use kcalloc instead of kzalloc to allocate arrayThomas Meyer1-1/+1
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 <[email protected]> Signed-off-by: Greg Kroah-Hartman <[email protected]>
