mxs-dma.c provides two functions mxs_dma_is_apbh and mxs_dma_is_apbx which are used at least in mxs-mmc.c. Building mxs-mmc as module fails due to those two symbols not being exported.

If i understand correctly, usually we add EXPORT_SYMBOL right below the function exported. And can we use EXPORT_SYMBOL_GPL? It seems both driver using this are gpl licensed. BTW, maybe you also need change the patch title format a bit: dma: mxs-dma: ... Regards Dong Aisheng
