+X-Git-Tag: v2.6.29-rc1~24^2~7
+X-Git-Url: http://git.kernel.org/?p=linux%2Fkernel%2Fgit%2Ftorvalds%2Flinux-2.6.git;a=commitdiff_plain;h=19cdd08ba155dd87ebb87bb39ed097dbee671e0e
+
+[S390] qdio: fix broken pointer in case of CONFIG_DEBUG_FS is disabled
+
+If CONFIG_DEBUG_FS is disabled debugfs_create_file returns -ENODEV instead
+of zero. Since the return value is stored and used at shutdown to remove
+existing entries an OOPS may be triggered.
+
+Add a check of the debugfs_create_file return value and in case of an error
+set the entry to NULL so it will be ignored at shutdown.
