WARNING: arch/arm/mach-iop13xx/built-in.o - Section mismatch: reference to .init.text:iop13xx_pcie_map_irq from .text between 'iop13xx_pci_setup' (at offset 0x7fc) and 'iop13xx_map_pci_memory' While fixing this warning I also recalled Adrian Bunk's recommendation to not use inline in .c files, as 'iop13xx_map_pci_memory' is needlessly inlined. Removing 'inline' uncovered some dead code so that is cleaned up as well. Signed-off-by: Dan Williams <dan.j.williams@intel.com> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
