From 703860ed4e36ded696bd44af6107243fdedfb746 Mon Sep 17 00:00:00 2001 From: Bjorn Helgaas Date: Wed, 17 Apr 2013 16:57:56 -0600 Subject: [PATCH] PCI: Use u8, not int, for PM capability offset The Power Management Capability (PCI_CAP_ID_PM == 0x01) is defined by PCI and must appear in the 256-byte PCI Configuration Space from 0-0xff. It cannot be in the PCIe Extended Configuration space from 0x100-0xfff, so we only need a u8 to hold its offset. Signed-off-by: Bjorn Helgaas Acked-by: Rafael J.
