I don't think the patch is correct, so I haven't bothered signing off on
it.  Probably the & is not correct in the IS_ERR call?

Subject: [PATCH] ASoC: fix odd_ptr_err.cocci warnings

 PTR_ERR should access the value just tested by IS_ERR

Semantic patch information:
 There can be false positives in the patch case, where it is the call to
 IS_ERR that is wrong.

Please take the patch only if it's a positive warning. Thanks!

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
