b44: Use kernel DMA addresses for the kernel DMA API
We must not use the device DMA addresses for the kernel DMA API, because device DMA addresses have an additional offset added for the SSB translation. Use the original dma_addr_t for the sync operation. Cc: stable@kernel.org Signed-off-by: Michael Buesch <mb@bu3sch.de> Signed-off-by: David S. Miller <davem@davemloft.net>
