Subject: [PATCH 06/17] can: dev: fix type of get_can_dlc() and get_canfd_dlc() macros
Date: Wed,  7 Oct 2020 23:31:48 +0200	[thread overview]
Message-ID: <20201007213159.1959308-7-mkl@pengutronix.de> (raw)
In-Reply-To: <20201007213159.1959308-1-mkl@pengutronix.de>

From: Vincent Mailhol <mailhol.vincent@wanadoo.fr>

The macros get_can_dlc() and get_canfd_dlc() are not visible in
userland. As such, type u8 should be preferred over type __u8.
