On the Keychron K8 keyboard, and probably others, the right side keys
should not be swapped to maintain PC layout.
Swapping the right side keys moves 'Super' before 'Alt gr' which is not
intended by the default Keychron layout or the ISO layout.

The iso_layout parameter must be manually set to get the driver to
swap KEY_102ND and KEY_GRAVE. This patch eliminates the need to do that.
This is safe to do, as Macs with keyboards that do not need the quirk
will keep working the same way as the value of hid->country will be
different than HID_COUNTRY_INTERNATIONAL_ISO. This was tested by one
person with a Mac with the WELLSPRINGT2_J152F keyboard with a layout
that does not require the quirk to be set.

The hid-apple driver does not support chaining translations or
dependencies on other translations. This creates two problems:
1 - In Non-English keyboards of Macs, KEY_102ND and KEY_GRAVE are
swapped and the APPLE_ISO_TILDE_QUIRK is used to work around this
problem. The quirk is not set for the Macs where these bugs happen yet
(see the 2nd patch for that), but this can be forced by setting the
iso_layout parameter. Unfortunately, this only partially works.
KEY_102ND gets translated to KEY_GRAVE, but KEY_GRAVE does not get
translated to KEY_102ND, so both of them end up functioning as
KEY_GRAVE. This is because the driver translates the keys as if Fn was
pressed and the original is sent if it is not pressed, without any
further translations happening on the key[#463]. KEY_GRAVE is present at
macbookpro_no_esc_fn_keys[#195], so this is what happens:
- KEY_GRAVE -> KEY_ESC (as if Fn is pressed)
- KEY_GRAVE is returned (Fn isn't pressed, so translation is discarded)
- KEY_GRAVE -> KEY_102ND (this part is not reached!)
...
2 - In case the touchbar does not work, the driver supports sending
Escape when Fn+KEY_GRAVE is pressed. As mentioned previously, KEY_102ND
is actually KEY_GRAVE and needs to be translated before this happens.
Normally, these are the steps that should happen:
- KEY_102ND -> KEY_GRAVE
- KEY_GRAVE -> KEY_ESC (Fn is pressed)
- KEY_ESC is returned
Though this is what happens instead, as dependencies on other
translations are not supported:
- KEY_102ND -> KEY_ESC (Fn is pressed)
- KEY_ESC is returned
This patch fixes both bugs by ordering the translations correctly and by
making the translations continue and not return immediately after
translating a key so that chained translations work and translations can
depend on other ones.
This patch also simplifies the implementation of the swap_fn_leftctrl
option a little bit, as it makes it simply use a normal translation
instead adding extra code to translate a key to KEY_FN[#381]. This change
wasn't put in another patch as the code that translates the Fn key needs
to be changed because of the changes in the patch, and those changes
would be discarded with the next patch anyway (the part that originally
translates KEY_FN to KEY_LEFTCTRL needs to be made an else-if branch of
the part that transltes KEY_LEFTCTRL to KEY_FN).
Note: Line numbers (#XYZ) are for drivers/hid/hid-apple.c at commit
20afcc4625 ("HID: apple: Add "GANSS" to the non-Apple list").
Note: These bugs are only present on Macs with a keyboard with no

Keychron's C-series and K-series of keyboards copy the vendor and
product IDs of an Apple keyboard, but only behave like that device when
set to "Mac" mode. In "Windows" mode, the Fn key doesn't generate a
scancode, so it's impossible to use the F1-F12 keys when fnmode is set
to its default value of 1.
To fix this, make fnmode default to the new value of 3, which behaves
like fnmode=2 for Keychron keyboards and like fnmode=1 for actual Apple
keyboards. This way, Keychron devices are fully usable in both "Windows"
and "Mac" modes, while behavior is unchanged for everything else.

The function key mapping for the Magic Keyboard first generation (2007,

This caused two main issues:
- The F5 and F6 keys were sending KEY_KBDILLUMDOWN and KEY_KBDILLUMUP;
however, the keyboard is not backlited.
- The keyboard has the APPLE_NUMLOCK_EMULATION quirk with F6 set as
the KEY_NUMLOCK key by "powerbook_numlock_keys". However, because F6
was mapped to KEY_KBDILLUMUP by the default mapping it was not
possible to switch the numlock status.
This means that, if numlock was enabled on session startup, it was
not possible to disable it without connecting another keyboard.

Some Apple ISO keyboards have a quirk where the backtick/tilde key is
swapped with the less-than/greater-than key. Unfortunately, there is no
perfectly reliable way to detect whether a keyboard has the quirk or
not, but the quirk appears to only be present on models that support
Bluetooth, and the affected keyboards usually report country code 13 in
the HID descriptor.
Therefore, the best we can do is to change
/sys/module/hid_apple/parameters/iso_layout to a ternary:
0 = Not ISO or ISO and not quirky
1 = ISO and quirky
-1 = Guess based on product ID and country code

The Maxxter KB-BT-001 Bluetooth keyboard, which looks somewhat like the
Apple Wireless Keyboard, is using the vendor and product IDs (05AC:0239)
of the Apple Wireless Keyboard (2009 ANSI version) <sigh>.
But its F1 - F10 keys are marked as sending F1 - F10, not the special
functions hid-apple.c maps them too; and since its descriptors do not
contain the HID_UP_CUSTOM | 0x0003 usage apple-hid looks for for the
Fn-key, apple_setup_input() never gets called, so F1 - F6 are mapped
to key-codes which have not been set in the keybit array causing them
to not send any events at all.
The lack of a usage code matching the Fn key in the clone is actually
useful as this allows solving this problem in a generic way.
This commits adds a fn_found flag and it adds a input_configured
callback which checks if this flag is set once all usages have been
mapped. If it is not set, then assume this is a clone and clear the
quirks bitmap so that the hid-apple code does not add any special
handling to this keyboard.
This fixes F1 - F6 not sending anything at all and F7 - F12 sending
the wrong codes on the Maxxter KB-BT-001 Bluetooth keyboard and on
similar clones.

It is safe to use devres allocation within the hid subsystem:
- the devres release is called _after_ the call to .remove(), meaning
that no freed pointers will exists while removing the device
- if a .probe() fails, devres releases all the allocated ressources
before going to the next driver: there will not be ghost ressources
attached to a hid device if several drivers are probed.
Given that, we can clean up a little some of the HID drivers. These ones
are trivial:
- there is only one kzalloc in the driver
- the .remove() callback contains only one kfree on top of hid_hw_stop()
- the error path in the probe is easy enough to be manually checked
