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.
