M68k allmodconfig still selects Sun-3, which sets NO_DMA.
I guess you're also seeing this on the other NO_DMA platforms (h8300, m32r,
s390, and PCI-less SPARC)?
Below is a patch.
Shouldn't it also (or instead) depend on SUPERH or some SuperH platform?
Or is this not done to have more compile-coverage?
Subject: [PATCH] VIDEO_SH_MOBILE_CEU should depend on HAS_DMA
commit 0d3244d6439c8c31d2a29efd587c7aca9042c8aa ("V4L/DVB (8342):
sh_mobile_ceu_camera: Add SuperH Mobile CEU driver V3") introduced
VIDEO_SH_MOBILE_CEU, which selects VIDEOBUF_DMA_CONTIG. This circumvents the
dependency on HAS_DMA of VIDEOBUF_DMA_CONTIG.
Add a dependency on HAS_DMA to VIDEO_SH_MOBILE_CEU to fix this.

The SUPERH dependency was there initially, but was dropped for increased
compilation coverage. The HAS_DMA dependence is certainly the right thing
to do here.
