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
persists it would be a little odd and we'd have to dig deeper:

dma-contiguous: fix !CONFIG_DMA_CMA version of dma_{alloc, free}_contiguous()
yes CONFIG_DMA_CMA is set (=y, see attached config), the commit you mention
above is included, if you have any hints how to go forward, please let me
For CONFIG_DMA_CMA=y, by judging the log with error code -12, I
feel this one should work for you. Would you please check if it
is included or try it out otherwise?

dma-contiguous: do not overwrite align in dma_alloc_contiguous()

Thanks for the hint, yet the commit is included and does not fix the problem!
