Subject: [PATCH] ASoC: fix odd_ptr_err.cocci warnings (fwd)

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?

 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!
