    Subject[PATCH 5.14 088/334] media: TDA1997x: enable EDID support
    Date
    From: Krzysztof Hałasa <khalasa@piap.pl>

    [ Upstream commit ea3e1c36e38810427485f06c2becc1f29e54521d ]

    Without this patch, the TDA19971 chip's EDID is inactive.
    EDID never worked with this driver, it was all tested with HDMI signal
    sources which don't need EDID support.
