bcache: fix return value error in bch_journal_read() When everything is OK in bch_journal_read(), finally the return value is returned by, return ret; which assumes ret will be 0 here. This assumption is wrong when all journal buckets as are full and filled with valid journal entries. In such cache the last location referencess read_bucket() sets 'ret' to 1, which means new jset added into jset list. The jset list is list 'journal' in caller run_cache_set(). Return 1 to run_cache_set() means something wrong and the cache set won't start, but indeed everything is OK. This patch changes the line at end of bch_journal_read() to directly return 0 since everything if verything is good. Then a bogus error is fixed.
