Merge branch 'remotes/lorenzo/pci/tegra'

- Drop return value checking for debugfs_create() calls (Greg
  Kroah-Hartman)

- Convert debugfs "ports" file to use DEFINE_SEQ_ATTRIBUTE() (Liu Shixin)

* remotes/lorenzo/pci/tegra:
  PCI: tegra: Convert to use DEFINE_SEQ_ATTRIBUTE macro
  PCI: tegra: No need to check return value of debugfs_create() functions
