Yes, IS_ERR() was called with the wrong argument.  I fixed it now.

Note that it's no branch to be merged to upstream yet, it's just a
testing for the previously submitted patchset.

Simon, my latest version is found in topic/soc-cx2072x branch in sound
git tree:
  git://git.kernel.org/pub/scm/linux/kernel/git/tiwai/sound.git

Please check that before the next submission.


thanks,

Takashi
