From 274127a1fdbad3c0d64e813521f4a0ef96cfc70e Mon Sep 17 00:00:00 2001 From: Alex Williamson Date: Tue, 17 Dec 2013 16:43:57 -0700 Subject: PCI: Rename PCI_VC_PORT_REG1/2 to PCI_VC_PORT_CAP1/2 These are set of two capability registers, it's pretty much given that they're registers, so reflect their purpose in the name.
