Robert Richter e0c818e004 cxl/pci: Get rid of pointer arithmetic reading CDAT table ... Reading the CDAT table using DOE requires a Table Access Response Header in addition to the CDAT entry. In current implementation this has caused offsets with sizeof(__le32) to the actual buffers. This led to hardly readable code and even bugs. E.g., see fix of devm_kfree() in read_cdat_data(): commit c65efe3685 ("cxl/cdat: Free correct buffer on checksum error") Rework code to avoid calculations with sizeof(__le32). Introduce struct cdat_doe_rsp for this which contains the Table Access Response Header and a variable payload size for various data structures afterwards to access the CDAT table and its CDAT Data Structures without recalculating buffer offsets.
