From: Willem de Bruijn idpf_tx_splitq_build_flow_desc performs a 32-bit store to &cmd_dtype to set the 8-bit cmd_dtype and zero the adjacent 3-byte timestamp field in a single operation. Descriptors are in little endian. Add missing cpu_to_le32 and cast to __le32 to ensure the fields are written correctly also on big endian platforms.
