Hi Christoph, After merging the dma-mapping tree, today's linux-next build (powerpc ppc64_defconfig) produced this warning:
drivers/base/platform.c:1182:12: warning: 'dma_default_get_required_mask'
defined but not used [-Wunused-function]
static u64 dma_default_get_required_mask(struct device *dev)
^~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Introduced by commit
dma_default_get_required_mask ("dma-mapping: make the get_required_mask
method available unconditionally")
It is only used in the case ARCH_HAS_DMA_GET_REQUIRED_MASK is not defined.
