extern void ttm_dma_unpopulate(struct ttm_dma_tt *ttm_dma, struct
device *dev);
We have forgotten to provide dummies for non SWIOTLB/IOMMU systems and
xtensa doesn't seem to have this.
And BTW please drop the "extern" keyword here, that is the default for
functions anyway.
The functions I added don't have extern. That being said I can write
two patches one that adds dummy functions and one that removes the
needless externs.
Cheers,
