Subject: powerpc: Get iseries to compile with ARCH=powerpc
X-Git-Tag: v2.6.15-rc1~59^2~203
X-Git-Url: https://err.no/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=76f9f87fa51c9fb62c17986e2066ed467ac2da05;p=linux-2.6

powerpc: Get iseries to compile with ARCH=powerpc

This moves the Device_List member from struct device_node to
struct pci_dn, which cleans up the device_node and makes the code
a little simpler.
