IS_ERR_VALUE() needs a pointer sized argument, so warn when any int
sized arguments sneak in. When this happens a warning is generated:
warning: cast to pointer from integer of different size [-Wint-to-pointer-cast]
Based on Kernel commit aa00edc1287a ("make IS_ERR_VALUE() complain about non-pointer-sized arguments")
