commit c7d0b2db5bc5e8c0fdc67b3c8f463c3dfec92f77 upstream.
MHI endpoint stack accidentally started allocating memory for objects from
DMA zone since commit 62210a26cd4f ("bus: mhi: ep: Use slab allocator
where applicable"). But there is no real need to allocate memory from this
naturally limited DMA zone. This also causes the MHI endpoint stack to run
out of memory while doing high bandwidth transfers.
So let's switch over to normal memory.
