[PATCH] hwmon: (yogafan) fix non-kernel-doc header warning

[Sergio Melas <sergiomelas@gmail.com>]

hwmon: (yogafan) Add support for Lenovo Yoga/Legion fan monitoring.

This driver provides fan speed monitoring for Lenovo Yoga, Legion, and
IdeaPad laptops by interfacing with the Embedded Controller (EC) via ACPI.

The current header comment starts with '/**', which is reserved for
kernel-doc, this triggers a warning so we update it starting to '/*'
to avoid the compile warning.

v11.1:
  - Fix comment header to resolve 0-day robot warning.
v11:
  - Mapped ACPI paths directly via DMI quirks.
  - Fixed Documentation formatting (0-day robot warnings).
  - Implemented 100ms MIN_SAMPLING to address rapid polling concerns.
  - Removed redundant platform_set_drvdata() in probe.
  - Explicitly defined platform device ID as -1 for cleaner sysfs naming.
v9/10:
  - Implement ACPI handle resolution during probe for better performance (O(1) read).
  - Add MODULE_DEVICE_TABLE(dmi, ...) to enable module autoloading.
  - Refine RLLag filter documentation and suspend/resume logic.
  - Include comprehensive EC architecture research database (8-bit vs 16-bit).
  - Validated efficiency on kernels 6.18, 6.19, and 7.0-rc5: 'perf top' 
    confirms negligible CPU overhead (<0.01%) during active polling.
v8:
  - Replaced heuristic multiplier with deterministic DMI Quirk Table.
  - Added 'depends on DMI' to Kconfig.
  - Verified FOPTD model (1000ms TAU / 1500 RPM/s slew) against hardware traces.
  - Increased filter precision to 12-bit fixed-point.
v7:
  - Fixed Kconfig: Removed non-existent 'select MATH64'.
  - Fixed unused macro: Utilized RPM_FLOOR_LIMIT to implement an
    immediate 0-RPM bypass in the filter.
  - Clarification: Previous "unified structure" comment meant that all
    6 files (driver, docs, metadata) are now in this single atomic patch.
v6:
  - Unified patch structure (6 files changed).
  - Verified FOPTD (First-Order Plus Time Delay) model against hardware
      traces (Yoga 14c) to ensure physical accuracy of the 1000ms time constant.
  - Fixed a rounding stall: added a +/- 1 RPM floor to the step calculation
    to ensure convergence even at high polling frequencies.
  - Set MAX_SLEW_RPM_S to 1500 to match physical motor inertia.
  - Documentation: Updated to clarify 100-RPM hardware step resolution.
  - 32-bit safety: Implemented div64_s64 for coefficient precision.
v5:
  - Fixed 32-bit build failures by using div64_s64 for 64-bit division.
  - Extracted magic numbers into constants (RPM_UNIT_THRESHOLD, etc.).
  - Fixed filter stall by ensuring a minimum slew limit (limit = 1).
  - Refined RPM floor logic to trigger only when hardware reports 0 RPM.
  - Resolved 255/256 unit-jump bug by adjusting heuristic thresholds.
v4:
  - Rebased on groeck/hwmon-next branch for clean application.
  - Corrected alphabetical sorting in Kconfig and Makefile.
  - Technical Validation & FOPTD Verification:
    - Implemented RLLag (Rate-Limited Lag) first-order modeling.
    - Used 10-bit fixed-point math for alpha calculation to avoid
      floating point overhead in the kernel.
    - Added 5000ms filter reset for resume/long-polling sanitation.
v3:
  - Added MAINTAINERS entry and full Documentation/hwmon/yogafan.rst.
  - Fixed integer overflow in filter math.
  - Added support for secondary fan paths (FA2S) for Legion laptops.
v2:
  - Migrated from background worker to passive multirate filtering.
  - Implemented dt-based scaling to maximize CPU sleep states.
  - Restricted driver to Lenovo hardware via DMI matching.
v1:
  - Initial submission with basic ACPI fan path support.
