You should be able to cherry pick the relevant commits over without too
much hassle?  Should be commits:

f8f1179d34d5adb3b0fe45327050470aae9b3d7e
28dcfbeb157c58ae24d5ba173984bfc316ca95ee
ed5457f91695784d692190b1b8ff024ae462801c

in that order.  ASoC generally backports fairly easily since it doesn't
have too many ties into fast-changing parts of the system - you can
often get a long way by simply copying soc-core.c, soc-dapm.c, soc.h and
soc-dapm.h into your current version.

Could you give that a spin and let me know if you can get something
sorted out?

I did also notice:

> +static int code_reg_open_file(struct inode *inode, struct file *file)

Not sure why I didn't notice this before but codec_reg rather than code_reg?

BTW, please CC me on ASoC patch submissions - it makes it harder for me
to miss things on the list.
