[PATCH] sbp2: fix check of return value of hpsb_allocate_and_register_addrspace()
From: Stefan Richter <stefanr@s5r6.in-berlin.de>
I added a failure check in patch "sbp2: variable status FIFO address (fix
login timeout)" --- alas for a wrong error value. This is a bug since
Linux 2.6.16. Leads to NULL pointer dereference if the call failed, and
bogus failure handling if call succeeded.
