Fix the problem by not calling dma_alloc_coherent() when the device
is not DMA capable, such as SDIO and USB.

ath10k calls dma_alloc_coherent multiple places including
ath10k_htt_rx_alloc.

Do SDIO and USB not use such data path function at all?

Good point! Maybe I am not just hitting these paths on my simple tests.

Kalle,

How should we handle this?

Thanks
