I overlooked the original report probably because I was not CCed.
This is introduced by commit a4e893e802e6("thermal: cpu_cooling:
Migrate to using the EM framework") which adds the dependency of
ENERGY_MODEL for THERMAL_GOV_POWER_ALLOCATOR.
To fix this, it's better to make THERMAL_DEFAULT_GOV_POWER_ALLOCATOR
depends on THERMAL_GOV_POWER_ALLOCATOR instead.
Please confirm the problem is fixed by below patch.
thanks,

Subject: [PATCH] thermal: fix a Kconfig warning
Currently, THERMAL_GOV_POWER_ALLOCATOR is selected by
THERMAL_DEFAULT_GOV_POWER_ALLOCATOR even if it has some unmet
dependencies.
This causes the Kconfig warning
WARNING: unmet direct dependencies detected for
THERMAL_GOV_POWER_ALLOCATOR
Depends on [n]: THERMAL [=y] && ENERGY_MODEL [=n]
Selected by [y]:
- THERMAL_DEFAULT_GOV_POWER_ALLOCATOR [=y] && <choice>
Fix the problem by making THERMAL_DEFAULT_GOV_POWER_ALLOCATOR depends on
THERMAL_GOV_POWER_ALLOCATOR instead.
