John Ogness e7c1fe2104 printk: ringbuffer: avoid memcpy() on state_var ... @state_var is copied as part of the descriptor copying via memcpy(). This is not allowed because @state_var is an atomic type, which in some implementations may contain a spinlock. Avoid using memcpy() with @state_var by explicitly copying the other fields of the descriptor. @state_var is set using atomic set operator before returning.
