+Subject: powerpc/pci: Fix annotation of pcibios_claim_one_bus
+X-Git-Url: http://git.kernel.org/?p=linux%2Fkernel%2Fgit%2Fbenh%2Fpowerpc.git;a=commitdiff_plain;h=baf75b0a42a1b3f6fca80f8949b6141eaff61b0d
+
+powerpc/pci: Fix annotation of pcibios_claim_one_bus
+
+It was __devinit, but it is also within a CONFIG_HOTPLUG guarded section
+of code, so the __devinit does nothing but cause the following warning:
+
+WARNING: vmlinux.o(.text+0x107a8): Section mismatch in reference from the function pcibios_finish_adding_to_bus() to the function .devinit.text:pcibios_claim_one_bus()
+The function pcibios_finish_adding_to_bus() references
+the function __devinit pcibios_claim_one_bus().
+This is often because pcibios_finish_adding_to_bus lacks a __devinit
+annotation or the annotation of pcibios_claim_one_bus is wrong.
+
+It is also only (externally) used in arch/powerpc/kernel/of_platform.c
+which cannot be built as a module so don't export it.
