TPM: ReadPubEK output struct fix
commit 02a077c52ef7631275a79862ffd9f3dbe9d38bc2 upstream.
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.
