4.1-stable review patch. If anyone has any objections, please let me know. ------------------ 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.
