Subject: PCI: tegra: Fix host bridge memory leakage
Git-commit: 792abc6e2f5a5ab996bf6cc1947b382dda29a82d
Patch-mainline: v4.13-rc1
References: fate#326572
When probing the PCI host controller driver, if an error occurs, the probe
function code does not free memory allocated for the struct pci_host_bridge
resulting in memory leakage.
Move the struct pci_host_bridge allocation over to the respective devm
interface to fix the issue.
