can: dev: make can_change_state() robust to be called with cf == NULL In OOM situations where no skb can be allocated, can_change_state() may be called with cf == NULL. As this function updates the state and error statistics it's not an option to skip the call to can_change_state() in OOM situations. This patch makes can_change_state() robust, so that it can be called with cf == NULL. Signed-off-by: Marc Kleine-Budde <mkl@pengutronix.de>
