Fix address argument of nand controller currently being
passed to dma_unmap_resource() in probe error path.
Sure, this looks more compact and simpler.
will use this for the title.
Unmap the right resource upon probe failure: we currently
provide the physical address of the DMA region rather than the
output of dma_map_resource() which is obviously wrong.
Will keep the rest in commit description. Thanks for this suggestion
This address argument should be the dma address returned by
dma_map_resource() instead of the physical address of nand controller.
