Subject: [PATCH] powerpc/pci: fix checking for child bridges in PCI code.
Date: Wed, 18 Aug 2010 12:27:55 -0600 [thread overview]
Message-ID: <20100818182727.29483.53699.stgit@angua> (raw)
pci_device_to_OF_node() can return null, and list_for_each_entry will
never enter the loop when dev is NULL, so it looks like this test is
a typo.
