38b9ab80db platform/x86: thinkpad_acpi: Move subdriver initialization to tpacpi_pdriver's probe. 
It was reported that if subdrivers assigned devres resources inside
ibm_init_struct's .init callbacks, driver binding would fail with the
following error message:

	platform thinkpad_acpi: Resources present before probing

Let the driver core manage the lifetimes of the subdrivers and children
devices, by initializing them inside tpacpi_driver's .probe callback.
This is appropriate because these subdrivers usually expose sysfs groups
and the driver core manages this automatically to avoid races.

One immediate benefit of this, is that we are now able to use devres
inside .init subdriver callbacks.

platform_create_bundle is specifically used because it makes the
driver's probe type synchronous and returns an ERR_PTR if attachment
failed.

Additionally, to make error handling simpler, allocate the input device
using devm_input_allocate_device().

8d5316c6c6 platform/x86: wmi: Update documentation regarding the GUID-based API 
Warn WMI driver developers to not use GUID-based and non-GUID-based
functions for querying WMI data blocks and handling WMI events
simultaneously on the same device, as this will corrupt the WMI device
state and might thus lead to erratic behaviour.

08c9f40290 platform/x86: wmi: Call WCxx methods when setting data blocks 
After performing some tests with a custom SSDT table available at
https://github.com/Wer-Wolf/acpi-wmi-ssdt i found out that Windows
also enables data block collection even when the data block is
being set.

Emulate this behaviour to avoid confusing the ACPI firmware.
The bus-based API already implements this behaviour, so only the
legacy GUID-based API needs to be changed.

656f0961d1 platform/x86: wmi: Rework WCxx/WExx ACPI method handling 
The handling of the WExx ACPI methods used for enabling and disabling
WMI events has multiple flaws:

- the ACPI methods are called even when the WMI device has not been
  marked as expensive.

- WExx ACPI methods might be called for inappropriate WMI devices.

- the error code AE_NOT_FOUND is treated as success.

The handling of the WCxx ACPI methods used for enabling and disabling
WMI data blocks is also flawed:

- WMI data blocks are enabled and disabled for every single "query"
  operation. This is racy and inefficient.

Unify the handling of both ACPI methods by introducing a common
helper function for enabling and disabling WMI devices.

Also enable/disable WMI data blocks during probe/remove and shutdown
to match the handling of WMI events.

Legacy GUID-based functions still have to enable/disable the WMI
device manually and thus still suffer from a potential race condition.
Since those functions are deprecated and suffer from various other
flaws this issue is purposefully not fixed.

b6b566908c platform/x86: wmi: Use devres to disable the WMI device 
Use devm_add_action_or_reset() to disable the WMI device instead of
manually calling wmi_method_enable() to prepare for future changes
inside the WMI data block handlign code.

The reason for this is that we have to make sure that all
devres-managed resources are released first because some might still
want to access the underlying WMI device.

Because devres-managed resources are not released during shutdown
we still have to manually disable the WMI device in this case.

b3e127daca platform/x86: thinkpad_acpi: Fix registration of tpacpi platform driver 
The recent platform profile changes prevent the tpacpi platform driver
from registering. This error is seen in the kernel logs, and the
various tpacpi entries are not created:

[ 7550.642171] platform thinkpad_acpi: Resources present before probing

This happens because devm_platform_profile_register() is called before
tpacpi_pdev probes (thanks to Kurt Borja for identifying the root
cause).

For now revert back to the old platform_profile_register to fix the
issue. This is quick fix and will be re-implemented later as more
testing is needed for full solution.

Tested on X1 Carbon G12.

21cc9dee7d platform/x86: alienware-wmi: Refactor LED control methods 
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.

898a2302d7 platform/x86: alienware-wmi: Add WMI Drivers 
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().

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 *.
