[PATCH v12 00/16] lenovo-wmi: Add fixes and enhancement

["Derek J. Clark" <derekjohn.clark@gmail.com>]

This series adds many much needed fixes and features to the lenovo-wmi*
drivers. This version has been re-ordered to ensure the least amount of
churn in each patch. This has resulted in two formatting patches being
added to the stable Cc list as prerequisites for some of the fixes.

Patches 1-9 fix various bugs and formatting, and are Cc'd to stable.
for the formatting only ones, patch 7 moves all gamezone enums from the
gamezone header into the helpers header and patch 8 adds two functions
to make assigning attribute ID's for capdata0X and tunable_attr_01
cleaner.

Patch 10 adds the remaining CPU attributes that weren't previously
exposed.

Patch 11 adds GPU attributes.

Patch 12 renames a name constant in preparation for patch 6.

Patch 13 adds battery charge-type limiting when supported only by WMI, or
when a module parameter to skip compatibility checks is set. The
MODULE_PARM_DESC macro creates one check and two warnings in checkpatch.
I reviewed other examples from the kernel and I am following the same
convention, so I left it as is.

Patch 14 adds a module parameter, force_load_psy_ext, to bypass ACPI and
BIOS compatibility checks for the power supply extension.

Patch 15 adds a debugfs directory.

Patch 16 adds a debugfs file for dumping capdata.

v12:
  - Break out force_load_psy_ext into its own patch.
  - Drop fixes tags for formatting only prerequisite patches Cc'd to
    stable.
  - Fix formatting in various places.
  - Use correct type when passing args in new functions. I will revisit
    & fix older functions in a new series.
v11: https://lore.kernel.org/platform-driver-x86/20260507180507.912966-1-derekjohn.clark@gmail.com/
  - Reorganize patches in a way that cleans up the churn with
    assignment of attribute IDs. This also allowed dropping the
    patch that moved the LWMI_FAN_DIV patch as it is now effectively
    moved when declaring the updated LWMI_ATTR_ID_FAN_DIV macro. As a
    result, some formatting only patches were added to the Cc list for
    stable since as they are now prerequisites to some of the fixes.
  - Refactor charge control patch to use charge_behavior and
    charge_control_end_threshold instead of charge_types to be in
    accordance with the power supply class documentation.
  - Minor additional formatting fixes.
v10: https://lore.kernel.org/platform-driver-x86/20260411162334.25682-1-derekjohn.clark@gmail.com/
  - Fix misnamed attribute in wmi-other.
v9: https://lore.kernel.org/platform-driver-x86/20260411162334.25682-1-derekjohn.clark@gmail.com/
  - Invert ida_alloc fail logic.
  - Fix dropped mode arg in current_value_show.
  - Fix misnamed attribute in documentation.
v8: https://lore.kernel.org/platform-driver-x86/20260406201400.438221-1-derekjohn.clark@gmail.com/
  - Clean up rebase mixup with re-assinment of wmi_method_args_32 in
    patches 6 and 14 from {} to { 0x00, 0x00 } and back.
  - Combine ret_obj declaration and assignment in patch 1.
v7: https://lore.kernel.org/platform-driver-x86/20260402032424.678528-1-derekjohn.clark@gmail.com/
  - Add 3 additional bug fix patches from Rong Zhang reported by
    shashiko.dev
  - Reorder patches so the fixes are upfront in patches 1-7.
  - Fix various typos and rebase mixups from v6.
v6: https://lore.kernel.org/platform-driver-x86/20260331181208.421552-1-derekjohn.clark@gmail.com/
  - Incorporate Rong Zhang's debugfs and decoupling patches into the
    series.
  - Add a patch to clean up too many cross-references to wmi-gamezone.h
  - Make lwmi_attr_id a static inline in wmi-capdata.h
  - Added a patch  to fix a bug where ares.arg1 is uninitialized when it
    is sent to the firmware.
  - Add supported checks before adding battery extenstion, and ensure
    both the new checks and the is_writable checks are not casting u32
    to i32.
  - Misc formating changes.
v5: https://lore.kernel.org/platform-driver-x86/20260324221032.1333636-1-derekjohn.clark@gmail.com/
  - Remove cv/cd_mode_id references that occured before patch 4.
  - Move lwmi_attr_id to capdata.c with a namespace export.
  - Fix mixing include.
  - Make lwmi_attr_is_supported return bool.
  - Use switch instead of if for setting/getting charge type state.
  - Various formatting fixes.
v4: https://lore.kernel.org/platform-driver-x86/20260312031032.3467565-1-derekjohn.clark@gmail.com/
  - Use loop instead of back gotos for identifying the working attribute
    ID.
  - Use function instead of macro to assign attribute_id, preserving
    types.
  - Removed unused defines and enum values.
  - Rename charging defines to clarify thier purpose.
  - Fixed various formatting issues from v3.
  - Added module param to skip ACPI check when loading the driver for
    the power supply extension.
  - Don't abort adding power supply extension if the ACPI handle from
    ideapad is not present.
  - Don't worry about symmetric cleanup when cleaning up attributes in
    an error state.
  - Reword Patch 8 commit message to be more concise.
  - Fix wording in Patch 7 to match the changes.
v3: https://lore.kernel.org/platform-driver-x86/20260224043200.2680384-1-derekjohn.clark@gmail.com/
  - Re-add HWMON name const and just rename LWMI_OM_FW_ATTR_BASE_PATH
  - Fix linker warnings by moving acpi/battery include to the end of the
    list.
  - Remove CPU/GPU OC features. These attributes are BOOL type and will
    need a new constructor that I'll add later.
v2: https://lore.kernel.org/platform-driver-x86/20260215061339.2842486-1-derekjohn.clark@gmail.com/
  - Fix gpu_mode misisng from attributes list.
  - Fix prototypes for power suppy patch.
  - Reorganize CPU and GPU attributes alphabetically.
  - Break out the patch consolidating the driver name cost.
  - Move some of the refactoring of attribute_id back to into patch 1
    where it belongs.
  - Fix some additional typos in function prototypes.
v1: https://lore.kernel.org/platform-driver-x86/20260213081243.794288-1-derekjohn.clark@gmail.com/
