Merge branch 'remotes/lorenzo/pci/tegra'

- Remove unused struct tegra_pcie_bus (Krzysztof Wilczyński)

* remotes/lorenzo/pci/tegra:
  PCI: tegra: make const array err_msg static
  PCI: tegra: Use 'seq_puts' instead of 'seq_printf'
  PCI: tegra: Fix OF node reference leak
  PCI: tegra: Remove unused struct tegra_pcie_bus
