Subject: [PATCH 3.12 31/72] tipc: don't log disabled tasklet handler errors

From: Erik Hugne <erik.hugne@...csson.com>

3.12-stable review patch.  If anyone has any objections, please let me know.

===============

[ Upstream commit 2892505ea170094f982516bb38105eac45f274b1 ]

Failure to schedule a TIPC tasklet with tipc_k_signal because the
tasklet handler is disabled is not an error. It means TIPC is
currently in the process of shutting down. We remove the error
logging in this case.
