Subject: [PATCH] ASoC: cht_bsw_rt5645: Use common error handling code in
 cht_codec_fixup()

* Add a jump target so that a specific error message is stored only once
  at the end of this function implementation.

* Replace two calls of the function "dev_err" by goto statements.

This issue was detected by using the Coccinelle software.
