There appears to be a mixture of u8 and unsigned char going on here, cf.
'smbios_header'.
While I'm pretty sure all architectures typedef them to be equivalent,
semantically, as a reviewer this makes me think there are type issues.
Is there any way to use one data type for the SMBIOS header?

Perhaps this should be -EINVAL? -ENODATA implies that if you try again
in the future data might be available, i.e. it's a temporary failure.
That's not the case here since the header is invalid.
