right, but even then using a dma pool seems to be a bit of overhead for only a few allocations. As far as I understood those pools are meant for hundrets or thousands of rather small chunks.
I dont want to criticise it though, since the code at this place is surely not wrong. My initial post was due to a misunderstanding of mine: I thought the third parameter of dma_pool_create() is the total allocation size of all chunks (dont ask me how I came to this conclusion, I could not explain it now :/ ).
