CEC still not working on raspberry pi 3 with current nightly builds

    Describe the bug

    Similar to this report CEC stopped working on RPi3+ on latest master for me.

    CEC (control via TV remote) worked before with Milhouse's LibreELEC-Builds. Unfortunately, test.libreelec.tv provides only a few images from past. Thus, I cannot reproduce when it stopped working.

    To Reproduce

    Steps to reproduce the behavior:

    1. Install latest nightly image on RPi3
    2. Connect to a CEC supported TV
    3. Enable CEC adapter in Kodi settings
    4. Try to use TV remote to control Kodi
