The use of > set_dma_ops() in this driver is questionable), Hi, The set_dma_ops() is no longer required in the fsl/fman, I'll send a patch to remove it.

Remove dependencies on HAS_DMA where a Kconfig symbol depends on another symbol that implies HAS_DMA, and, optionally, on "|| COMPILE_TEST". In most cases this other symbol is an architecture or platform specific symbol, or PCI. Generic symbols and drivers without platform dependencies keep their dependencies on HAS_DMA, to prevent compiling subsystems or drivers that cannot work anyway. This simplifies the dependencies, and allows to improve compile-testing. Notes: - FSL_FMAN keeps its dependency on HAS_DMA, as it calls set_dma_ops(), which does not exist if HAS_DMA=n (Do we need a dummy? The use of set_dma_ops() in this driver is questionable), - SND_SOC_LPASS_IPQ806X and SND_SOC_LPASS_PLATFORM loose their dependency on HAS_DMA, as they are selected from SND_SOC_APQ8016_SBC.
