Subject: [PATCH v3 1/4] can: slcan: use can_dropped_invalid_skb() instead of manual check
Date: Sat, 14 May 2022 23:16:47 +0900 [thread overview]
Message-ID: <20220514141650.1109542-2-mailhol.vincent@wanadoo.fr> (raw)
In-Reply-To: <20220514141650.1109542-1-mailhol.vincent@wanadoo.fr>
slcan does a manual check in slc_xmit() to verify if the skb is
valid. This check is incomplete, use instead
can_dropped_invalid_skb().
