The name "cea_vendor_block" implies that it's a generic container for
vendor block encodings.  Something more like:

struct cea_vendor_block_hdmi {
    unsigned char portB:4;
    unsigned char portA:4;
    unsigned char portD:4:
    unsigned char portC:4;
    unsigned char support_flags;
    unsigned char max_tmds_clock;
    unsigned char latency_present;
    unsigned char video_latency;
    unsigned char audio_latency;
    unsigned char interlaced_video_latency;
    unsigned char interlaced_audio_latency;
};

/* other vendor block types */

struct cea_vendor_block {
    unsigned char ieee_id[3];
    union {
        struct cea_vendor_block_hdmi hdmi;
        /* any other vendor blocks we know about */
    } u;
};

perhaps?
