PCI: fix 4x section mismatch warnings
The following warnings were issued during build of drivers/pci with an allyesconfig build: WARNING: o-x86_64/drivers/pci/built-in.o(.text+0xdaf): Section mismatch in reference from the function pci_add_new_bus() to the function .devinit.text:pci_alloc_child_bus() WARNING: o-x86_64/drivers/pci/built-in.o(.text+0x15e2): Section mismatch in reference from the function pci_scan_single_device() to the function .devinit.text:pci_scan_device() WARNING: o-x86_64/drivers/pci/built-in.o(.text+0x1b0c5): Section mismatch in reference from the function pci_bus_assign_resources() to the function .devinit.text:pci_setup_bridge() WARNING: o-x86_64/drivers/pci/built-in.o(.text+0x1b32d): Section mismatch in reference from the function pci_bus_size_bridges() to the function .devinit.text:pci_bus_size_cardbus() Investigating each case closer it looked like all referred functions are only used in the init phase or during hotplug. So to avoid wasting too much memory in the non-hotplug case the simpler fix was to allow the fuctions to use code/data from the __devinit sections. This was done in all four case by adding the __ref annotation. Signed-off-by: Sam Ravnborg <sam@ravnborg.org> Cc: Adrian Bunk <bunk@kernel.org> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
