[PATCH v2 3/3] drm: xlnx: dpsub: Fix DMADEVICES Kconfig dependency

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



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.
