mkfs.jffs2 failed to create repeated dev nodes from device_table.txt

[Thomas Chou]

Hi experts,

I found an issue with the latest git head. The mkfs.jffs2 failed to 
create repeated dev nodes from the device_table.txt in the git tree, 
such as hda1-15, tty0-5.

It happened with this pattern,

/dev/tty	c	666	0	0	5	0	0	0	-
/dev/tty	c	666	0	0	4	0	0	1	6

# IDE Devices
/dev/hda	b	640	0	0	3	0	0	0	-
/dev/hda	b	640	0	0	3	1	1	1	15
/dev/hdb	b	640	0	0	3	64	0	0	-
/dev/hdb	b	640	0	0	3	65	1	1	15


Using jffs2dump -c, I could see only hda,

          Dirent     node at 0x004d3970, totlen 0x0000002b, #pino    14, 
version   274, #ino       276, nsize        3, name hda
          Inode      node at 0x004d399c, totlen 0x00000046, #ino    276, 
version     1, isize        0, csize        2, dsize        2, offset 
      0

Best regards,
Thomas
