Subject: BUG: cannot enable iso_layout with apple keyboard

Hi,

I have an apple keyboard model A1644 EMC 2815 with Finnish/Swedish ISO layout. When I connect it via cable it works fine. But when I connect it via bluetooth, then the buttons >/< and §/° are swapped. It seems to make no difference if I set iso_layout to 0 or to 1. I checked and it turns out that hid->country below equals 0, and removing the check

diff --git a/drivers/hid/hid-apple.c b/drivers/hid/hid-apple.c

                        trans = apple_find_translation(apple_iso_keyboard, usage->code);
                        if (trans) {

        if (swap_opt_cmd) {

makes the buttons act correctly. Please let me know how I can help fixing this.
