Subject[PATCH 3.10 22/46] SUNRPC: Fix a module reference leak in svc_handle_xprt
Date
3.10-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Trond Myklebust <trond.myklebust@primarydata.com>

commit c789102c20bbbdda6831a273e046715be9d6af79 upstream.

If the accept() call fails, we need to put the module reference.
