6.6-stable review patch. If anyone has any objections, please let me know.

From: Thomas Fourier fourier.thomas@gmail.com
commit 21140e5caf019e4a24e1ceabcaaa16bd693b393f upstream.
The dma_unmap_sg() functions should be called with the same nents as the dma_map_sg(), not the value the map function returned.
