3.12.15-rt26-rc1 stable review patch.
If anyone has any objections, please let me know.

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

From: "Steven Rostedt (Red Hat)" <rostedt@goodmis.org>

The patch "net: gianfar: do not try to cleanup TX packets if they are
not done" for 3.12-rt left out the return value for gfar_clean_tx_ring().
This would cause an error when building this module. Note, this module
does not build on x86 and was not tested because of that.
