It\ncompletely ignored the fact that the function was passed `num_blocks`\nwhich indicated how much memory had been allocated for the EDID.\n\nLet's fix this by adding a bounds check.\n\nThis is important for handling the case where there's an error in the\nfirst block of the EDID. In that case we will call\nconnector_bad_edid() without having re-allocated memory based on\n`edid[0x7e]`."
