4.9-stable review patch. If anyone has any objections, please let me know.
------------------
From: Julian Scheel <julian@xxxxxxxx>
commit 7ac45d1635a4cd2e99a4b11903d4a2815ca1b27b upstream.
In case cpu could not be found the error message would always refer to
/codec/ not being found in DT. Fix this by catching the cpu node not found
case explicitly.
