It's not allowed to create an alias of system RAM for DMA. So the memory used must not be allocated using dma_alloc_coherent but has to be reserved before using memblock routines. There is no need to memzero the buffer because dma_alloc_coherent zeros the memory for us. Signed-off-by: Uwe Kleine-K?nig <redacted>
Thank you very much for this patch ! Regards, Philippe
