From: Ignacy Gawędzki <[email protected]> 3.12-stable review patch. If anyone has any objections, please let me know.
=============== [ Upstream commit 34eea79e2664b314cab6a30fc582fdfa7a1bb1df ] In tcf_em_validate(), after calling request_module() to load the kind-specific module, set em->ops to NULL before returning -EAGAIN, so that module_put() is not called again by tcf_em_tree_destroy().
