* 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.
Indeed this isn't very smart to provide the same test but no, this is
the wrong way to fix this. The error message is in reply to two
different configurations, one on the codec side and one on the cpu-dai
side. We should change the error message to more clearly indicate the
issue rather than fold both cases under the same handler.
Besides this is the same code as in other machine drivers so needs to be
handled in multiple files as well.
