I encountered the same. Turns out, you need to disable OSLEC in your codec
.config, and delete the modules in your /lib/modules/[kernel
version]/drivers/staging directory, and then (in your kernel sources)
make && make modules && make modules install

The dahdi tools actually contains an out-of-tree version that worked out of
the box.
