struct MPI2_RAID_SCSI_IO_REQUEST ends with a single SGL, but expects to copy multiple. Add a flexible array member so the compiler can reason about the size of the memcpy(). This will avoid the run-time false positive warning: memcpy: detected field-spanning write (size 128) of single field "&r1_cmd->io_request->SGL" at drivers/scsi/megaraid/megaraid_sas_fusion.c:3326 (size 16) This change results in no binary output differences.
