[ 071/150] PCI: Fix PCI Express Capability accessors for PCI_EXP_FLAGS

From: Greg Kroah-Hartman
Date: Tue Feb 26 2013 - 20:04:15 EST


3.8-stable review patch. If anyone has any objections, please let me know.

------------------

From: Alex Williamson <alex.williamson@xxxxxxxxxx>

commit 969daa349f4821a02936af7202b51a9affc7b6da upstream.

PCI_EXP_FLAGS_TYPE is a mask, not an offset. Fix it.

Previously, pcie_capability_read_word(..., PCI_EXP_FLAGS, ...) would
fail.
