Is cc_code really in little endian? I would expect data in smbios to be
in native endian (ie. u16), bios using different endian than the host
sounds strange to me. And struct dmi_header also uses native endian:

struct dmi_header {
	u8 type;
	u8 length;
	u16 handle;
} __packed;

Yes, Kalle,

I agree with you.

need I send new version to change the "__le16 cc_code" to "u16 cc_code"?
