[PATCH] klist: Fix broken kref counting in find functions
The klist reference counting in the find functions that use klist_iter_init_node is broken. If the function (for example driver_find_device) is called with a NULL start object then everything is fine, the first call to next_device()/klist_next increases the ref-count of the first node on the list and does nothing for the start object which is NULL. If they are called with a valid start object then klist_next will decrement the ref-count for the start object but nobody has incremented it. Logical place to fix this would be klist_iter_init_node because the function puts a reference of the object into the klist_iter struct.
