[BUG] platform/x86: hp-wmi: PWM_MODE_AUTO sends speed=0 which turns fan off on 8C77

Hello platform maintainers,
On an HP OMEN laptop (DMI board 8C77, BIOS F.20), returning the fan from
manual/max control back to automatic via the in-tree hp-wmi driver does not
resume EC/firmware cooling. The fans drop to 0 RPM and stay there even while
the CPU package temperature keeps rising past ~97 C. This is dangerous (fan
shut-off under load).
Environment
-----------
Steps to reproduce
------------------
echo 0 > pwm1_enable # max (works: fans -> ~6000 RPM, pwm 255)
echo 2 > pwm1_enable # PWM_MODE_AUTO -> fans ramp to 0 and stay
Observed timeline
-----------------
t(s) pwm1 enable fan1 fan2 x86_pkg_temp
0 255 0 6000 6300 ~89 C
+2 229 2 5400 5600 ~92 C
+6 34 2 800 1200 ~92 C
+10 0 2 0 0 ~96 C
+16 0 2 0 0 ~98 C (still rising)
Expected: fans resume a temperature curve (as on Windows/OMEN).
Actual : fans stop at 0 RPM and never resume, while the package heats up.
(Same also happens when going idle -> auto.)
Root cause (from driver + ACPI/fw tables)
----------------------------------------
hp_wmi_apply_fan_settings() PWM_MODE_AUTO calls hp_wmi_fan_speed_max_reset(),
which sets cpu/gpu_pwm = HP_FAN_SPEED_AUTOMATIC (0x00) and then
hp_wmi_fan_speed_set() sends fan speed 0x00 to the EC
(VICTUS_S_FAN_SPEED_SET / GM). On board 8C77 the EC treats speed 0 as
"fan off", not "release to automatic", so it never resumes the automatic
curve.
The board's ACPI DSDT (from the BIOS dump) confirms the EC interface:
EC mailbox : OperationRegion (ECCD, SystemMemory, 0xFE0B0800, 0x1000)
EC read/write: ERRD/ERWT, command bytes 0xB0 (read) / 0xB1 (write);
fan PWM at EC offsets 0xB0..0xB3
EmbeddedCtrl : OperationRegion (ERAM, EmbeddedControl, ...) offsets 0x5F/0x62
Thermal prof.: EC offset 0x95 (HP_OMEN_EC_THERMAL_PROFILE_OFFSET);
balanced 0x30 / perf 0x31 / cool 0x50
Suggested fix direction
-----------------------
On PWM_MODE_AUTO, after clearing the manual fan speed, also re-assert the EC
thermal profile to balanced (e.g. omen_thermal_profile_set(DEFAULT) /
thermal_profile_set()) so the EC takes back control, OR stop sending
HP_FAN_SPEED_AUTOMATIC (0x00) to the EC on boards that treat 0 as off.
I can upload the full BIOS ACPI dump / raw FIT image if useful. Happy to
test a proposed patch on real hardware.
Thanks,
