TPM: ReadPubEK output struct fix
This patch adds a missing element of the ReadPubEK command output, that prevents future overflow of this buffer when copying the TPM output result into it. Prevents a kernel panic in case the user tries to read the pubek from sysfs. Signed-off-by: Rajiv Andrade <srajiv@linux.vnet.ibm.com> Signed-off-by: James Morris <jmorris@namei.org>
