Subject: [PATCH 3/3] drm: xlnx: dpsub: Fix DMADEVICES Kconfig dependency
Date: Wed, 29 Jul 2020 19:29:10 +0300 [thread overview]
Message-ID: <20200729162910.13196-4-laurent.pinchart@ideasonboard.com> (raw)
In-Reply-To: <20200729162910.13196-1-laurent.pinchart@ideasonboard.com>
The dpsub driver uses the DMA engine API, and thus selects DMA_ENGINE to
provide that API. DMA_ENGINE depends on DMADEVICES, which can be
deselected by the user, creating a possibly unmet indirect dependency:
WARNING: unmet direct dependencies detected for DMA_ENGINE
Depends on [n]: DMADEVICES [=n]
Selected by [m]:
- DRM_ZYNQMP_DPSUB [=m] && HAS_IOMEM [=y] && (ARCH_ZYNQMP || COMPILE_TEST [=y]) && COMMON_CLK [=y] && DRM [=m] && OF [=y]
Add a dependency on DMADEVICES to fix this.
