Message-Id: <1452400870-6005-5-git-send-email-peter@hurleysoftware.com> Date: Sat, 9 Jan 2016 20:40:55 -0800 From: Peter Hurley <peter@...leysoftware.com> To: Greg Kroah-Hartman <gregkh@...uxfoundation.org> Cc: Jiri Slaby <jslaby@...e.cz>, linux-kernel@...r.kernel.org, Peter Hurley <peter@...leysoftware.com> Subject: [PATCH v2 04/19] NFC: nci: Remove dead code The N_NCI ldisc does not define a flush_buffer() ldisc method, so the check when opening the ldisc is always false.
