Sorry, but I don't get what the problem is, the Fixes line generated by the
command is identical with the line in the commit. What am I missing?

In commit

  db50fb87015b95 ("iommu/dma-iommu: Fix wrong scatterlist length assignment in P2PDMA path")

Fixes tag

  Fixes: a25e7962db ("PCI/P2PDMA: Refactor the p2pdma mapping helpers")

has these problem(s):

  - SHA1 should be at least 12 digits long
    This can be fixed for the future by setting core.abbrev to 12 (or
    more) or (for git v2.11 or later) just making sure it is not set
    (or set to "auto").
