[PATCH] dcdbas: dcdbas_pdev referenced after platform_device_unregister on exit
smi_data_buf_free() references dcdbas_pdev when calling
dma_free_coherent(). In dcdbas_exit(), smi_data_buf_free() is called after
platform_device_unregister(dcdbas_pdev).
This patch moves platform_device_unregister(dcdbas_pdev) after
smi_data_buf_free() in dcdbas_exit().
