[PATCH 0/2] platform/x86: hp-wmi: Add manual fan support for Victus S laptops

[Krishna Chomal]

This series adds support for manual fan speed control and PWM reporting
for HP Victus S-style laptops.

The first patch refactors the hwmon implementation to use a per-device
private context for state tracking. It implements RPM-to-PWM conversion
using linear interpolation based on the laptop's internal fan tables
retrieved via WMI. It also introduces PWM_MODE_MANUAL, allowing users
to set specific fan speeds.

The second patch addresses a firmware-specific behavior where the
system reverts to "Auto" fan mode after a 120-second timeout if no WMI
fan commands are received. A delayed workqueue is implemented to act
as a keep-alive heartbeat, refreshing the fan state every 90 seconds
to ensure user-selected profiles remain active indefinitely.

Tested on: HP Omen 16-wf1xxx (board ID 8C78)
