The dev->dma_mask usually points to dev->coherent_dma_mask. This is an
issue as setting both of them will override the other. This is
problematic here as the PPv2 driver uses a 32-bit-mask for coherent
accesses (txq, rxq, bm) and a 40-bit mask for all other accesses due to
an hardware limitation.

That's the problem that needs to be fixed then.

OK, I'll drop this patch until I find a pr
