resolved:\n\nthermal: core: Fix thermal zone governor cleanup issues\n\nIf thermal_zone_device_register_with_trips() fails after adding\na thermal governor to the thermal zone being registered, the\ngovernor is not removed from it as appropriate which may lead to\na memory leak.\n\nIn turn, thermal_zone_device_unregister() calls thermal_set_governor()\nwithout acquiring the thermal zone lock beforehand which may race with\na governor update via sysfs and may lead to a use-after-free in that\ncase.\n\nAddress these issues by adding two thermal_set_governor() calls, one to\nthermal_release() to remove the governor from the given thermal zone,\nand one to the thermal zone registration error path to cover failures\npreceding the thermal zone device registration."}],
