Wen Yang reported that some CEC drivers incremented the refcount of the HDMI device, but never decremented it, potentially leading to memory leaks. Rather than fixing each driver I decided to create a helper function that finds the HDMI device and handles the refcounting correctly. Two drivers (seco-cec and cros-ec-cec) still required a manual patch.
