+From: Gerald Schaefer <geraldsc@de.ibm.com>
+Subject: kernel: Fix initialization of stp.
+References: bnc#440610
+
+Symptom:     The stp support cannot be activated.
+Problem:     The return code of chsc_sstpc changed from 1 for success to
+             0 for success. The stp_reset function still tests for 1 and
+             does not set the indication that stp support is available.
+Solution:    Check for the correct return code of chsc_sstpc.
+
+Acked-by: John Jolly <jjolly@suse.de>
