Move prototype declaration of function to header file include/linux/swiotlb.h from arch/ia64/hp/common/hwsw_iommu.c, arch/ia64/hp/common/sba_iommu.c and arch/x86/pci/sta2x11-fixup.c because it is used by more than one file.
This eliminates the following warning in lib/swiotlb.c: lib/swiotlb.c:240:1: warning: no previous prototype for ‘swiotlb_late_init_with_default_size’ [-Wmissing-prototypes] lib/swiotlb.c:537:13: warning: no previous prototype for ‘map_single’ [-Wmissing-prototypes] Signed-off-by: Rashika Kheria <rashika.khe...@gmail.com> Reviewed-by: Josh Triplett <j...@joshtriplett.org> --- arch/ia64/hp/common/hwsw_iommu.c | 3 --- arch/ia64/hp/common/sba_iommu.c | 2 -- arch/x86/pci/sta2x11-fixup.c | 1 - include/linux/swiotlb.h | 4 +++- 4 files changed, 3 insertions(+), 7 deletions(-) diff --git a/arch/ia64/hp/common/hwsw_iommu.c b/arch/ia64/hp/common/hwsw_iommu.c index 1e4cae5..b14cab1 100644 --- a/arch/ia64/hp/common/hwsw_iommu.c +++ b/arch/ia64/hp/common/hwsw_iommu.c @@ -20,9 +20,6 @@ extern struct dma_map_ops sba_dma_ops, swiotlb_dma_ops; -/* swiotlb declarations & definitions: */ -extern int swiotlb_late_init_with_default_size (size_t size); - /* * Note: we need to make the determination of whether or not to use * the sw I/O TLB based purely on the device structure.
