[PATCH] mkfs.jffs2: fix dir creation in /

[Mike Frysinger]

With older mtd-utils, creating a directory in the root worked fine.  With
current git, the parent dir search algo breaks this.

For example, just take the current git tree, build it up, and then run:
$ ./mkfs.jffs2 -d . -D device_table.txt -o /dev/null
mkfs.jffs2: skipping device_table entry '/dev': no parent directory!
mkfs.jffs2: skipping device_table entry '/dev/mem': no parent directory!
...
Doing `mkdir ./dev` first works around the issue, but where's the fun in
that.
