Code looks OK. The markdown file is missing copyright statement. Please fix the commiter email. This is what the automated checks are complaining about:

Invalid email for Committer: root@hu-naveenks-hyd.qualcomm.com

Set the email in the repository (or globally)

git config user.email your_email@address
git congig user.name "Your Name"

After that rewrite the commit

git commit --amend -s --reset-author
