fix xen_swiotlb_dma_mmap prototype
xen_swiotlb_dma_mmap was backported from v4.10, but older kernels before commit 00085f1efa38 ("dma-mapping: use unsigned long for dma_attrs") use a different signature: arm/xen/mm.c:202:10: error: initialization from incompatible pointer type [-Werror=incompatible-pointer-types] .mmap = xen_swiotlb_dma_mmap, ^~~~~~~~~~~~~~~~~~~~ arm/xen/mm.c:202:10: note: (near initialization for 'xen_swiotlb_dma_ops.mmap') This adapts the patch to the old calling conventions. Fixes: "swiotlb-xen: implement xen_swiotlb_dma_mmap callback" Signed-off-by: Arnd Bergmann <arnd@arndb.de> Reviewed-by: Stefano Stabellini <sstabellini@kernel.org> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
