[PATCH 04/12] dma-mapping: fix DMA_OPS dependencies

From: Christoph Hellwig
Date: Tue Sep 08 2020 - 12:53:30 EST


Driver that select DMA_OPS need to depend on HAS_DMA support to
work. The vop driver was missing that dependency, so add it, and also
add a nother depends in DMA_OPS itself. That won't fix the issue due
to how the Kconfig dependencies work, but at least produce a warning
about unmet dependencies.
