can: SJA1000 add missing spin_lock_init()
As remarked by Sam Ravnborg the spin_lock variable, that has been introduced in commit 57c8a456640fa3ca777652f11f2db4179a3e66b6 ("can: Fix SJA1000 command register writes on SMP systems") has not been initialized properly. This patch adds the initialization to allow spinlock debugging. Signed-off-by: Oliver Hartkopp <socketcan@hartkopp.net> CC: Sam Ravnborg <sam@ravnborg.org> Signed-off-by: David S. Miller <davem@davemloft.net>
