This patch fixes the TPM's pubek sysfs entry that is accessible as long as the TPM doesn't have an owner. It was necessary to shift the access to the data by -10 -- the first byte immediately follows the 10 byte header. The line data = tpm_cmd.params.readpubek_out_buffer; sets it at the offset '10' in the packet, so we can read the data array starting at offset '0'.
