[PATCH v2 3/3] thermal: gov_power_allocator: Suppress sustainable_power warning without trip_points

[Nikita Travkin via B4 Relay]

From: Nikita Travkin <nikita@xxxxxxx>

IPA warns if the thermal zone it was attached to doesn't define
sustainable_power value. In some cases though IPA may be bound to an
"empty" TZ, in which case the lack of sustainable_power doesn't matter.

Suppress the warning in case when IPA is bound to an empty TZ to make it
easier to see the warnings that actually matter.

I've decided to add this along to supress those warnings for some TZ on
sc7180. Feel free to drop this patch if you think the warning should
always appear.
