Subject: [PATCH v3 2/7] can: dev: fix type of get_can_dlc() and get_canfd_dlc() macros
Date: Sat,  3 Oct 2020 00:41:46 +0900	[thread overview]
Message-ID: <20201002154219.4887-3-mailhol.vincent@wanadoo.fr> (raw)
In-Reply-To: <20201002154219.4887-1-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.
