From: Randy Dunlap <[email protected]> Fix kconfig warnings & build errors caused by DRM_ZYNQMP_DPSUB.
Any driver that selects DMA_ENGINE should make sure that DMADEVICES is already enabled. As is, this causes build errors in many other drivers. See https://lore.kernel.org/lkml/202009020239.ouph82xc%[email protected]/ for the numerous build errors.
