From ef1a85b6ca093abb00fbc38ea55fd9ae08ab05ef Mon Sep 17 00:00:00 2001 From: Christoph Hellwig Date: Sat, 29 Aug 2020 10:40:28 +0200 Subject: [PATCH] dma-mapping: fix DMA_OPS dependencies 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 another 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.
