I added an entry and copied the 0x0 value for the offset\nfrom similar code in drivers/gpu/drm/amd/display/modules/hdcp/hdcp_ddc.c.\n\nI also declared several of these arrays as having HDCP_MESSAGE_ID_MAX\nentries.  This doesn't change the code, but it's just a belt and\nsuspenders approach to try future proof the code."
