[uClibc] mkcramfs bug: devicelist and subdirs

[Chris Wilson]

Hi Erik,

I think I found a small bug in your cramfs patch, which I guess you ported 
from mkfs.jffs2.c. Therefore this bug might apply to mkfs.jffs2.c as well.

When searching for a file (or device node) to create in a subdirectory, 
mkcramfs doesn't remove the parent's path component which it's already 
matched. This prevents the sought node from ever being found if it lives 
in a subdirectory. This was triggered by "/dev/net/tun" in the supplied 
device_table.txt, since mkcramfs cannot find "/dev/net" in order to 
create the "tun" entry inside it. The attached patch should fix it.

Right, that's three patches for one day, I'm going home now :-)

Cheers, Chris.
