Another approach is to use ~0UL if that is preferable. >>> + list_for_each_entry(rentry, &resource_list, node) >>> + resources[count++] = *rentry->res; >> It has similarities with acpi_create_platform_device(). >> I guess we can utilize existing code. > For sure, this particular segment is effectively same as part of > acpi_create_platform_device(): Not the same, acpi_create_platform_device() does a bit more than copying the resources.
