Subject: vTPM: set virtual device before passing to ibmvtpm_reset_crq
From: "Hon Ching \\(Vicky\\) Lo" <honclo@xxxxxxxxxxxxxxxxxx>
commit 9d75f08946e8485109458ccf16f714697c207f41 upstream.
tpm_ibmvtpm_probe() calls ibmvtpm_reset_crq(ibmvtpm) without having yet
set the virtual device in the ibmvtpm structure. So in ibmvtpm_reset_crq,
the phype call contains empty unit addresses, ibmvtpm->vdev->unit_address.
