Subject: [PATCH 1/9] can: af_can: export can_sock_destruct()
Date: Wed, 13 Nov 2019 10:55:42 +0100	[thread overview]
Message-ID: <20191113095550.26527-2-mkl@pengutronix.de> (raw)
In-Reply-To: <20191113095550.26527-1-mkl@pengutronix.de>

From: Oleksij Rempel <o.rempel@pengutronix.de>

In j1939 we need our own struct sock::sk_destruct callback. Export the
generic af_can can_sock_destruct() that allows us to chain-call it.

Fixes: 9d71dd0c7009 ("can: add support of SAE J1939 protocol")
