This patch series:
  - Removes dependencies on HAS_DMA for symbols that already have
    platform dependencies implying HAS_DMA.

To avoid allmodconfig/allyesconfig regressions on NO_DMA=y platforms,
this (drivers) series should be applied after the previous (core)
series (but not many people may notice/care ;-)

Changes compared to v1:
  - Add Reviewed-by, Acked-by,
  - Drop dependency of SND_SOC_LPASS_IPQ806X on HAS_DMA,
  - Drop dependency of VIDEOBUF{,2}_DMA_{CONTIG,SG} on HAS_DMA,
  - Drop new dependencies of VIDEO_IPU3_CIO2, DVB_C8SECTPFE, and
    MTD_NAND_MARVELL on HAS_DMA,
  - Split in per-subsystem patches,
  - Split-off the core part in a separate series.

This series is against v4.16-rc5. It can also be found at
https://git.kernel.org/pub/scm/linux/kernel/git/geert/linux-m68k.git/log/?h=no-dma-compile-testing-v2

It has been compile-tested with allmodconfig and allyesconfig for
m68k/sun3, and has received attention from the kbuild test robot.

Do these patches have any dependencies? Can they be applied directly
in a subsystem tree?

Apart from introducing build failures in allmodconfig/allyesconfig builds on
(uncommon) NO_DMA=y platforms, they can be applied directly and individually.
