Wentao Liang 52f251dbfb mtd: rawnand: Add status chack in r852_ready() ... commit b79fe18299 upstream. In r852_ready(), the dev get from r852_get_dev() need to be checked. An unstable device should not be ready. A proper implementation can be found in r852_read_byte(). Add a status check and return 0 when it is unstable.
