Subject: [Yaffs] Building yaffs2 as a module for Ubuntu 12.10 fails.

This is what I have done:


git clone git://kernel.ubuntu.com/ubuntu/ubuntu-quantal.git
git clone git://www.aleph1.co.uk/yaffs2
cd ubuntu-quantal
git checkout -b 3.5.0-21.32-yaffs2 Ubuntu-3.5.0-21.32
cd ../yaffs2
./patch-ker.sh c m ../ubuntu-quantal/
cd ../ubuntu-quantal

Ensured that kernel configuration is OK, i.e. yaffs2 is configured as module

then `make`

At the end it spits out:
