2.6.38-stable review patch. If anyone has any objections, please let us know.
------------------ From: Roberto Sassu <[email protected]> commit 1821df040ac3cd6a57518739f345da6d50ea9d3f upstream. The pointer '(*auth_tok_key)' is set to NULL in case request_key() fails, in order to prevent its use by functions calling ecryptfs_keyring_auth_tok_for_sig().
