[confirmed we have a CLA on file which covers this email address]

Hrm. I do not know what we do in this case.

Elsewhere in the file I see, e.g., Ajay Berwal is listed as both
ajay.berwal@samsung.com and a.berwal@samsung.com, and there are already commits
under olli.syrjara@intel.com in the repository. So I expect that means both
emails should be listed. Maybe:

Olli Raula <olli.raula@intel.com>
Olli Raula (Old name Olli Syrjälä) <olli.syrjala@intel.com>

Then again, there do seem to be other commits that update email addresses, so
perhaps the duplicate lines are an anomaly and this change is correct.

Other Chromium people: how is this file supposed to be maintained?
