Subject: [PATCH net-next 05/18] can: sun4i_can: continue to use likely() to check skb

From: Dario Binacchi <dario.binacchi@...rulasolutions.com>

Throughout the sun4i_can_err() function, the likely() macro is used to
check the skb buffer, except in one instance. This patch makes the code
consistent by using the macro in that case as well.
