Subject: [PATCH] gpio: uapi: Improve phrasing around arrays representing empty strings
Date:   Tue,  3 Mar 2020 21:01:48 +0100
Message-Id: <20200303200149.27370-1-j.neuschaefer@gmx.net>
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: quoted-printable
Sender: linux-kernel-owner@vger.kernel.org
Precedence: bulk

Character arrays can be considered empty strings (if they are
immediately terminated), but they cannot be NULL.
