Subject: [PATCH v2 2/7] tty: Remove trailing whitespace
Date: Fri, 19 Oct 2018 09:37:02 +1100 [thread overview]
Message-ID: <20181018223707.9891-3-tobin@kernel.org> (raw)
In-Reply-To: <20181018223707.9891-1-tobin@kernel.org>
Currently files under drivers/tty/ contain trailing whitespace. This is
easy to fix and easy to review so lets do it now before we do other
kernel-docs cleanups.
