Add logic in enable_thermal_genl_check to avoid thermal-hal being woken up all the time by on-die sensor. When the temperature of the on-die sensor thermal_zone updates, the thermal_zone_device_update() will be called to handle thermal and then the netlink events will be sent through thermal_notify_tz_trip_(). But there is currently no way to filter thermal_zone in the thermal_netlink, so many netlink events will be sent in a short amount of time. Because the on-die sensors are very sensitive. Their temperature may jump up and down quickly in a few ms. Bug: 170682696 Test: boot and thermal-hal can receive thermal genl events from kernel Change-Id: Idb3f4b07a2a2740c01d8785910878bfe6edc832d Signed-off-by: davidchao <davidchao@google.com>
