is build on top of fixes material, and to bring lenovo related changes
in sync after the move under lenovo/ subdir in the for-next branch and

This reverts commit 5ff79cabb2.
Although the Alienware m16 R1 AMD model supports G-Mode, it actually has
a lower power ceiling than plain "performance" profile, which results in
lower performance.

To avoid passing an uninitialized `temp_id` to awcc_get_fan_label(),
pass the `fan_temps` bitmap instead, to work only on set bits.
Additionally, awcc_get_fan_label() leaves `dev` unused, so remove it
from it's signature and it does not fail, so remove error handling.

All models with the "AWCC" WMAX device support a way of manually
controlling fans.
The PWM duty cycle of a fan can't be controlled directly. Instead the
AWCC interface let's us tune a fan `boost` value, which has the
following empirically discovered, approximate behavior over the PWM
value:
pwm = pwm_base + (fan_boost / 255) * (pwm_max - pwm_base)
Where the pwm_base is the locked PWM value controlled by the FW and
fan_boost is a value between 0 and 255.
Expose this fan_boost knob as a custom HWMON attribute.
