Subject: drm: xlnx: dpsub: Fix DMADEVICES Kconfig dependency
Git-commit: 3e8b2403545efd46c6347002e27eae4708205fd4
Patch-mainline: v5.9-rc5
References: jsc#SLE-12680, jsc#SLE-12880, jsc#SLE-12882, jsc#SLE-12883, jsc#SLE-13496, jsc#SLE-15322
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.
