Revision 7b66dfcc6e1e1f018492619c3d0fc432b6b54272 authored by Liang He on 12 July 2022, 09:56:23 UTC, committed by Marc Kleine-Budde on 20 July 2022, 08:20:19 UTC
We should use of_node_put() for the reference returned by of_get_child_by_name() which has increased the refcount. Fixes: 45721c406dcf ("can: rcar_canfd: Add support for r8a779a0 SoC") Link: https://lore.kernel.org/all/20220712095623.364287-1-windhl@126.com Signed-off-by: Liang He <windhl@126.com> Signed-off-by: Marc Kleine-Budde <mkl@pengutronix.de>
