+Subject: [PATCH] fs/hfsplus: Set a grub_errno if mount fails
+
+It was possible for mount to fail but not set grub_errno. This led to
+a possible double decrement of the module reference count if the NULL
+page was mapped.
+
+Fixing in general as a similar bug was fixed in commit 61b13c187
+(fs/hfsplus: Set grub_errno to prevent NULL pointer access) and there
+are likely more variants around.
