Subject: kunit: move string-stream.h to lib/kunit
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=109fb06fdc6f6788df7dfbc235f7636a38e28fd4;p=linux.git

kunit: move string-stream.h to lib/kunit

string-stream interfaces are not intended for external use;
move them from include/kunit to lib/kunit accordingly.
