Hi Tobias,

do you have CONFIG_DMA_CMA set in your config?  If not please make sure
you have this commit in your testing tree, and if the problem still

commit dd3dcede9fa0a0b661ac1f24843f4a1b1317fdb6
Author: Nicolin Chen <nicoleotsuka@gmail.com>
Date:   Wed May 29 17:54:25 2019 -0700

    dma-contiguous: fix !CONFIG_DMA_CMA version of dma_{alloc, free}_contiguous()
