thermal: of-thermal: Fix setting of set_emul_temp hook
Currently thermal zone set_emul_temp is set unconditionally with of_thermal_set_emul_temp function. Set this only if the set_emul_temp hook is provided for thermal_zone_of_device_ops. This fixes emul_temp failures on platforms for which set_emul_temp hook is not populated. Fixes: "184a4bf623f (thermal: of: Extend current of-thermal.c code to allow setting emulated temp)" Suggested-by: Eduardo Valentin <edubezval@gmail.com> Signed-off-by: Keerthy <j-keerthy@ti.com> Signed-off-by: Eduardo Valentin <edubezval@gmail.com> Conflicts: drivers/thermal/of-thermal.c Signed-off-by: Zhang Rui <rui.zhang@intel.com>
