#1679738 — [PATCH v3 1/2] acpi: thermal: initialize tz_enabled to 1

FromEnric Balletbo i Serra <enric.balletbo@collabora.com>

Subject[PATCH v3 1/2] acpi: thermal: initialize tz_enabled to 1
Message-ID<tZ4AG-6PE-19@gated-at.bofh.it>
From: Sameer Nanda <snanda@chromium.org>

In the acpi_thermal_add path, acpi_thermal_get_info gets called before
acpi_thermal_register_thermal_zone.  Since tz_enabled was getting set to
1 only in acpi_thermal_register_thermal_zone, acpi_thermal_get_info
ended up disabling thermal polling.

Moved setting of tz_enabled to 1 into acpi_thermal_add itself.

Changes since v2:
 - Zhang Rui: 
   - Make sure tz->tz_enabled is set properly before registering the zone.

Changes since v1:
 - This patch is new from v1 [1]

Rui,

Can I just apply this, or do I need to work for a thermal core update?
 In the latter case, can you take care of this one too, please?

Thanks,
Rafael
