Subject: kernel/audit_tree.c: tree will leak memory when failure occurs in audit_trim_trees()

From: Chen Gang <gang.chen@xxxxxxxxxxx>

commit 12b2f117f3bf738c1a00a6f64393f1953a740bd4 upstream.

audit_trim_trees() calls get_tree().  If a failure occurs we must call
put_tree().

[akpm@xxxxxxxxxxxxxxxxxxxx: run put_tree() before mutex_lock() for small scalability improvement]
