[ Upstream commit cf96921876dcee4d6ac07b9de470368a075ba9ad ]
Some devices can have some thermal sensors disabled from the factory. The current two irq handler functions check all the sensor by default and the check if the sensor was actually registered is wrong. The tzd is actually never set if the registration fails hence the IS_ERR check is wrong.
