4.8-stable review patch. If anyone has any objections, please let me know.
------------------ From: Gavin Shan <[email protected]> commit a7032132d7560a8434e1f54b71efd7fa20f073bd upstream. The hub diag-data type is filled with big-endian data by OPAL call opal_pci_get_hub_diag_data(). We need convert it to CPU-endian value before using it. The issue is reported by sparse as pointed by Michael Ellerman: eeh-powernv.c:1309:21: warning: restricted __be16 degrades to integer This converts hub diag-data type to CPU-endian before using it in pnv_eeh_get_and_dump_hub_diag().
