I wouldn't really put inline here or in the function below.

I know it is just copy'n'paste but how about:

	if (dmabounce_sync_for_cpu(dev, handle, size, dir))
		__dma_single_dev_to_cpu(dma_to_virt(dev, handle), size, dir);
+}

+static inline void dma_sync_single_for_device(struct device *dev,
+		dma_addr_t handle, size_t size, enum dma_data_direction dir)
+{
+	BUG_ON(!valid_dma_direction(dir));
+
+	debug_dma_sync_single_for_device(dev, handle, size, dir);
+
+	if (!dmabounce_sync_for_device(dev, handle, size, dir))
+		return;
+
+	__dma_single_cpu_to_dev(dma_to_virt(dev, handle), size, dir);
Same as above.
+}
