Neither 'Hello' nor 'have a good day' are part of the change log.

Also please write the changelog in a factual way and not in form of a
question. If you want to add a reference to a git commit, then please
use the canonical form as described in Documentation/process, where you
also find the general patch submission rules. There is also a tip tree
specific chapter:

https://www.kernel.org/doc/html/latest/process/maintainer-tip.html?highlight=x86#patch-submission-notes

Following these rules makes everyones life simpler.

There is no NULL initialization required.
