Subject: linux-next: build failure after merge of the final tree (net-next
 tree related)

Hi all,

After merging the final tree, today's linux-next build (powerpc
allyesconfig) failed like this:

drivers/net/built-in.o: In function `pci_get_domain_bus_and_slot':
(.opd+0x449e8): multiple definition of `pci_get_domain_bus_and_slot'
drivers/pci/built-in.o:(.opd+0x1c98): first defined here

Caused by commit 13159183ec7a ("qlcnic: 83xx base driver") from the
net-next tree.  Why is this commit adding a function that already exists
globally?

I added this patch for today:

Subject: [PATCH] qlcnic: do not duplicate infrastructure functions
