* include/grub/raid.h (struct grub_raid_array): Change type of `device'
        to a grub_disk_t array.
        * disk/raid.c (grub_raid_read): Replace `device[x].disk' accesses with
        `device[x]'.
        (grub_raid_scan_device): Replace `device[x].name' accesses with
        `device[x]->name'.  Simplify initialization of `array->device[x]'.
