You should preserve the changelog of what has changed in each version, not only
the last changes, so that there is a logical flow and the maintainers do not
have to dig up previous versions:

Changes in v3:
- Update subject line.

Changes in v2:
- Fix "Fixes" tag.


Also, for this type of fixes, make sure to always Cc lkml: linux-kernel@...r.kernel.org

Thanks
