You are importing a file from a different repository, produced by a
different company. As part of that import, you are claiming Intel
copyright for 2019 for the code provided in the patch.

This means that you are making a legal claim to the intellectual
property provided by the patch on behalf of Intel.
Either:
- you have modified the code compared to the original, at which
  point the commit mesage *must* reflect this - it is no longer the
  contribution that the original message describes.
  For an example, see how Laszlo reflected his changes to 94e0dd1afe53.
- the Intel copyright addition is a mistake (and must be dropped).
