Subject: linux-next: build failure after merge of the pm tree
Hi Rafael,
After merging the pm tree, today's linux-next build (powerpc
ppc64_defconfig) failed like this:

Caused by commit 14d76b68f281 ("PCI: Use common resource list
management code instead of private implementation") interacting with
commit d2be00c0fb5a ("of/pci: Free resources on failure in
of_pci_get_host_bridge_resources()") from the pci tree.
I applied the following merge fix patch (which may need more work?).
Someone needs to remember to tell Linus about this fix (or similar)
when these trees get merged.
