[PATCH] spinlock not locked when unlocking in atm_dev_register

From: Frode Isaksen (fisaksen@bewan.com)

If you compile the kernel with SMP and spinlock debugging, BUG() will be
called when registering your atm driver, since the "atm_dev_lock" spinlock is
not locked when unlocking it.

kernel 2.4.18

Frode
