Subject: [PATCH 1/2] ASoC: qcom: change PTR_ERR argument

Apply PTR_ERR to the value that was recently assigned.

The semantic match that finds this problem is as follows:
(http://coccinelle.lip6.fr/)

// <smpl>
@@
expression x,y;
@@

if (IS_ERR(x) || ...) {
  ... when any
      when != IS_ERR(...)
(
   PTR_ERR(x)
|
*  PTR_ERR(y)
)
  ... when any
}
// </smpl>
