[PATCH] ppc64: uniform usage of bus unit id interfaces
01-pci-dn-uniformization.patch This patch changes the rtas_pci interface to use the new struct pci_dn structure for two routines that work with pci device nodes. This patch also does some minor janitorial work: it uses some handy macros and cleans up some trailing whitespace in the affected file.
