Both dma_unmap_sgtable() and sg_free_table() in spi_unmap_buf_attrs()
have checks for orig_nents against 0. No need to duplicate this.
All the same applies to other DMA mapping API calls.
Also note, there is no other user in the kernel that does this kind of
checks.

Hi,
this commit caused a regression which I reported here:
https://lore.kernel.org/all/d3679496-2e4e-4a7c-97ed-f193bd53af1d@notapiano
along with some thoughts on the cause and a possible solution, though I'm not
familiar with this code base at all and would really appreciate any feedback you
may have.
I also see the same regression on the SM8550 and SM8650 platforms,
please CC linux-arm-msm@xxxxxxxxxxxxxxx and me for a potential fix to test on those platforms.
Thanks,
Neil
