[PATCH 09/12] uio: UIO_DMEM_GENIRQ should depend on HAS_DMA

[Geert Uytterhoeven]

If NO_DMA=y:

drivers/built-in.o: In function `uio_dmem_genirq_release':
drivers/uio/uio_dmem_genirq.c:95: undefined reference to `dma_free_coherent'
drivers/built-in.o: In function `uio_dmem_genirq_open':
drivers/uio/uio_dmem_genirq.c:61: undefined reference to `dma_alloc_coherent'
