While the patch does not fix the timeout issue (also verified using an
Alt board), it does fix this follow-up issue here:

[ 191.485194] ------------[ cut here ]------------
[ 191.490296] WARNING: CPU: 0 PID: 698 at kernel/dma/debug.c:498 add_dma_entry+0x158/0x180
[ 191.499397] DMA-API: exceeded 7 overlapping mappings of cacheline 0x0117cc3a

So, I think we want this patch nonetheless but I need to rephrase the
commit message.
