Attached is the new patch without NULL dereference checks. I looked at grub_strchr and grub_strrchr calls as much as I can, and they don't seem to rely on NULL dereference behavior. But it was not feasible to verify this for some cases, as we are using function pointers (like, grub_disk_dev->open, etc.).
