[PATCH 5.4 24/57] i2c: amd-mp2-pci: Fix Oops in amd_mp2_pci_init() error handling

[Greg Kroah-Hartman]

From: Dan Carpenter <dan.carpen...@oracle.com>

commit ac2b0813fceaf7cb3d8d46c7b33c90bae9fa49db upstream.

The problem is that we dereference "privdata->pci_dev" when we print
the error messages in amd_mp2_pci_init():

        dev_err(ndev_dev(privdata), "Failed to enable MP2 PCI device\n");
                ^^^^^^^^^^^^^^^^^
