From 829a1985e732698ee98def146410e6e9f532781f Mon Sep 17 00:00:00 2001 From: Stefan Richter Date: Sun, 4 Jun 2006 02:51:40 -0700 Subject: [PATCH] [PATCH] sbp2: fix check of return value of hpsb_allocate_and_register_addrspace() From: Stefan Richter 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.
