In build_cdat_table() we do: *cdat_table = g_malloc0(sizeof(*cdat_table) * CXL_USP_CDAT_NUM_ENTRIES); This is wrong because: - cdat_table has type CDATSubHeader *** - so *cdat_table has type CDATSubHeader ** - so the array we're allocating here should be items of type CDATSubHeader * - but we pass sizeof(*cdat_table), which is sizeof(CDATSubHeader **), implying that we're allocating an array of CDATSubHeader ** It happens that sizeof(CDATSubHeader **) == sizeof(CDATSubHeader *) so nothing blows up, but this should be sizeof(**cdat_table). Avoid this excessively hard-to-understand code by using g_new0() instead, which will do the type checking for us. While we're here, we can drop the useless check against failure, as g_malloc0() and g_new0() never fail. This fixes Coverity issue CID 1508120.
