Subject: [PATCH v4 00/12] platform/x86: alienware-wmi-wmax: HWMON support +
 DebugFS + Improvements

Hi all,

This set mainly adds hwmon and manual fan control support (patches 7-8)
to the alienware-wmi driver, after some improvements.

I have a question for anyone that may know how to solve it. In version 2
of these series the kernel test robot found a build error

	https://lore.kernel.org/platform-driver-x86/202503051819.bQ9P70Og-lkp@intel.com/

I think this happened because

	CONFIG_ALIENWARE_WMI=y

while

	CONFIG_ACPI_PLATFORM_PROFILE=m
	CONFIG_HWMON=m

How should I Kconfig to avoid this?

Thank you for your feedback :)

Changes in v4:

[03/12]
  - Dropped awcc_profile_id_to_pprof because it's no longer used for
    pwm*_enable attributes

[07/12]
  - Dropped pwm*_enable visibility
  - Dropped fan_data->related_temps
  - Allocate fan_data->auto_channels_temp statically
  - Allocate priv->temp_sensors statically
  - Determine and allocate fan label while probing

[08/12]
  - Dropped pwm*_enable attributes because it's incompatible with
    current ABI
  - Renamed pwm*_boost attributes to fan*_boost
  - Added dev_err logs to awcc_hwmon_suspend/resume

[11/12]
  - Introduced laptop documentation

[12/12]
  - Introduced ABI documentation
