The CEC interrupt is really only needed when the CEC device is unconfigured and you want to monitor the CEC pin with high precision. The current code enables the irq for a short period when it is first requested, and for a short while just before the CEC device is configured. None of this is needed, so rework the code to ensure it is only enabled when it is really needed. In addition, the pin framework will now log the interrupt state in the debugfs status file.
