Currently the sm501 mfd driver can be compiled without any dependencies, but through the use of dma_declare_coherent it really depends on having DMA and iomem support. Normally we don't explicitly require DMA support as we have stubs for it if on UML, but in this case the driver selects support for dma_declare_coherent and thus also requires memmap support. Guard this by an explicit dependency. Signed-off-by: Christoph Hellwig <hch@lst.de> --- drivers/mfd/Kconfig | 1 + 1 file changed, 1 insertion(+)
