[PATCH v2 1/7] um: Add missing trailing newline to help messages

[Tiwei Bie]

From: Tiwei Bie <tiwei.btw at antgroup.com>

Some help messages are missing a trailing newline. They should
end with two newlines, but only one is present. Add the missing
newline to make the --help output more readable.
