Message-Id: <20201109153657.17897-4-socketcan@hartkopp.net>
Date: Mon, 9 Nov 2020 16:36:52 +0100
From: Oliver Hartkopp <socketcan@...tkopp.net>
To: linux-can@...r.kernel.org, mkl@...gutronix.de,
mailhol.vincent@...adoo.fr
Cc: netdev@...r.kernel.org, Oliver Hartkopp <socketcan@...tkopp.net>
Subject: [PATCH v5 3/8] can: remove obsolete get_canfd_dlc() macro
The macro was always used together with can_dlc2len() which sanitizes the
given dlc value on its own.
Signed-off-by: Oliver Hartkopp <socketcan@...tkopp.net>
