I noticed this while merging the drm tree and checking for stragglers:
the vsp1 driver still used dma_[alloc|free]_writecombine() that got
renamed in commit f6e45661 ("dma, mm/pat: Rename
dma_*_writecombine() to dma_*_wc()")

I should have noticed back in the media merge (commit bace3db5), but
better late than never.
