2009-07-13  Pavel Roskin  <pro...@gnu.org>

        * kern/device.c (grub_device_iterate): Change struct part_ent to
        hold the name, not a pointer to it.  Use one grub_malloc() per
        partition, not two.  Free partition_name if grub_malloc() fails.
        Set ents to NULL only before grub_partition_iterate() is called.
