Several source files reference swiotlb_late_init_with_default_size with an extern prototype; declare it in linux/swiotlb.h instead.
This also ensures that lib/swiotlb.c has a matching prototype for swiotlb_late_init_with_default_size, keeping the types in sync, and eliminating warnings from GCC (-Wmissing-prototypes) and Sparse (-Wdecl). lib/swiotlb.c:207:1: warning: no previous prototype for ‘swiotlb_late_init_with_default_size’ [-Wmissing-prototypes] Signed-off-by: Josh Triplett <j...@joshtriplett.org> --- arch/ia64/hp/common/sba_iommu.c | 3 +-- arch/x86/pci/sta2x11-fixup.c | 2 +- include/linux/swiotlb.h | 1 + 3 files changed, 3 insertions(+), 3 deletions(-) diff --git a/arch/ia64/hp/common/sba_iommu.c b/arch/ia64/hp/common/sba_iommu.c index bcda5b2..d37d4af 100644 --- a/arch/ia64/hp/common/sba_iommu.c +++ b/arch/ia64/hp/common/sba_iommu.c @@ -38,6 +38,7 @@ #include <linux/iommu-helper.h> #include <linux/dma-mapping.h> #include <linux/prefetch.h> +#include <linux/swiotlb.h> #include <asm/delay.h> /* ia64_get_itc() */ #include <asm/io.h> @@ -46,8 +47,6 @@ #include <asm/acpi-ext.h> -extern int swiotlb_late_init_with_default_size (size_t size); - #define PFX "IOC: " /* diff --git a/arch/x86/pci/sta2x11-fixup.c b/arch/x86/pci/sta2x11-fixup.c index 9d8a509..27dde02 100644 --- a/arch/x86/pci/sta2x11-fixup.c +++ b/arch/x86/pci/sta2x11-fixup.c @@ -26,9 +26,9 @@ #include <linux/pci_ids.h> #include <linux/export.h> #include <linux/list.h> +#include <linux/swiotlb.h> #define STA2X11_SWIOTLB_SIZE (4*1024*1024) -extern int swiotlb_late_init_with_default_size(size_t default_size); /* * We build a list of bus numbers that are under the ConneXt.
