Add a state container for the "alienware-wmi" platform device and
initialize it on the new alienfx_probe(). Migrate all LED control functions
to use this state container to support upcoming file split.
Additionally move the led_classdev registration to the platform driver
probe and make it device managed.
Drop alienware_zone_init() and alienware_zone_exit() because they are no
longer needed and mimic the `quirks->num_zone > 0` check by failing the
platform device probe.

Add WMI drivers for LEGACY and WMAX devices.
This involves moving the platform device registration to a helper
function that is now called from the driver's preferred WMI device
driver probe. In the case of the WMAX this is done only if
`!quirks->thermal` because the newer WMAX interface doesn't support any
of the LED features of this driver. This also eliminates the need to
check for `quirks->num_zones > 0` inside alienfx_probe().
The platform_driver's probe type is also set to PROBE_FORCE_SYNCHRONOUS
so we can create WMAX-only sysfs groups from within the probe without
races.
Only one WMI driver is registered on module initialization to prevent
registering a duplicate platform device.
Additionally, create_thermal_profile() now takes wmi_device * instead of
platform_device *.

Refactor all thermal control methods to use the newly defined awcc_priv
state container instead of global variables. While at it, rename
create_thermal_profile() to awcc_platform_profile_init() and introduce
alienware_awcc_setup() to set up the "AWCC" WMI device driver data.

Both WMI devices handled by this module specify a distinct interface for
LED control. Previously this module handled this by dynamically adapting
arguments passed to wmi_evaluate_method() based on the `interface`
global variable.
To avoid the use of global variables, and enable the migration to
non-deprecated WMI methods, let the WMI drivers define upd_led and
upd_brightness operations, which completely replace
alienware_update_led() and wmax_brightness().
Also define alienware_wmi_command(), which serves as a wrapper for
wmidev_evaluate_method(). This new method is very similar to
alienware_wmax_command() but is WMI device agnostic.

Split thermal features into a new DMI table to support upcoming file
split. While at it:
Rename quirk_entry -> alienfx_quirks,
Rename quirks -> alienfx
and change hdmi_mux, amplifier and deepslp types to bool, because they are
already being implicitly used as bools.

Which is why .dev_groups should be used as it is able to avoid those
races on driver core level.
Why you call device_add_groups() at all? Can't you just insert it into
.dev_groups member in alienware_wmax_wmi_driver?

In previous discussions with Armin we agreed it made more sense to move
WMAX-only groups from alienware-wmi-base.c to alienware-wmi-wmax.c when
splitting.
I have no problem in moving them back to .dev_groups though.

I'd love to do this as it would simplify things a LOT, but some
user-space tools might expect this attributes to be exposed by the
"fake" platform device located at
/sys/devices/platform/alienware-wmi
If it were not for this, I would expose every attribute in the WMI
device.

Ah, sorry, I didn't pay attention where they were added to. I vaguely
recall that discussion.
But still, you could make the groups available through .h and just add
them directly into alienfx_groups (with an #ifdef/#else in .h), or is
there again something I don't see?
Obviously, .is_visible functions need to be extended slightly to filter
out by interface but that should be relatively easy too. Also, the group
variable names should be properly prefixed when making them cross file
boundary like that.

What do you think about something like:
alienware-wmi.h
---------------
#if IS_ENABLED(CONFIG_ALIENWARE_WMI_WMAX)
#define WMAX_ONLY_GROUP(name) (wmax_##name)
extern const struct attribute_group wmax_hdmi_attribute_group;
...
#else
#define WMAX_ONLY_GROUP(name) NULL
#endif
alienware-wmi-base.c
--------------------
...
static const struct attribute_group *alienfx_groups[] = {
&zone_attribute_group,
WMAX_ONLY_GROUP(hdmi_attribute_group),
WMAX_ONLY_GROUP(amplifier_attribute_group),
WMAX_ONLY_GROUP(deepsleep_attribute_group),
NULL
...
};

IMHO, just define WMAX_GROUPS in the header and use it here.
Similar to e.g. ARCH_PCI_DEV_GROUPS in drivers/pci/pci-sysfs.c.

Thanks for the example, I was overthinking it. I'll send a v8 with this
approach!

Using PROBE_FORCE_SYNCHRONOUS is not going to solve this problem here, please remove it.

I'm curious too!
I found it while searching for something like devm_device_add_groups
which it turns out, was removed from the kernel.

Yes, I'm going for Ilpo's .dev_groups approach.
