From 18d590eee08be63b5971a4e2a80d571c86b3a305 Mon Sep 17 00:00:00 2001 From: Gavin Shan Date: Thu, 20 Oct 2016 14:17:17 +1100 Subject: pci: make PCI slot state as incremental to base number Various backends define their own PCI slot states for flexibility with numbers [A]. PCI core also defines its PCI slot states [B]. For one specific PCI slot state, the major number of [A] and [B] should be same so that the corresponding operation can be found. It means [A] and [B] are relevant to some extent, but the code where defines the PCI slots in backends doesn't reflect it. This makes the major PCI slot state defined in backend same to the corresponding one defined in PCI core. The minor PCI slot states are made to be incremental to their base number (major PCI slot state). No functional changes introduced.
