Hi all,

After merging the tip tree, today's linux-next build (arm
multi_v7_defconfig) produced this warning:

lib/swiotlb.c:748:13: warning: 'swiotlb_free_buffer' defined but not used [-Wunused-function]
static bool swiotlb_free_buffer(struct device *dev, size_t size,
^~~~~~~~~~~~~~~~~~~
lib/swiotlb.c:706:1: warning: 'swiotlb_alloc_buffer' defined but not used [-Wunused-function]
swiotlb_alloc_buffer(struct device *dev, size_t size, dma_addr_t *dma_handle,
^~~~~~~~~~~~~~~~~~~~

Introduced by commit

16e73adbca76 ("dma/swiotlb: Remove swiotlb_{alloc,free}_coherent()")

These are now only used with CONFIG_DMA_DIRECT_OPS.
