We definitely need a way to catch an invalid driver data pointer, but it
looks like that needs to be reworked after Vicky's patch.
Vicky could you look at all uses of ibmvtpm_get_data and make
sure we don't blindly dereference it? eg:
static int tpm_ibmvtpm_resume(struct device *dev)
{
struct ibmvtpm_dev *ibmvtpm = ibmvtpm_get_data(dev);
...
rc = plpar_hcall_norets(H_ENABLE_CRQ,
ibmvtpm->vdev->unit_address);
