The last two paragraphs should not be a part of the commit message. You'd
better place them in the section under "---", where you already have a
paragraph on v19 changes.

The commit message should definitely be more verbose. You should at least
list the devices used in the new machine.

If you have similar situations in other patches, they should be fixed too.

Yours, Aleksandar
