From: Dan Carpenter <dan.carpen...@oracle.com>
commit 0530ef6b41e80c5cc979e0e50682302161edb6b7 upstream.
The "drvdata->atclk" clock is optional, but if it gets set to an error
pointer then we're accidentally return an uninitialized variable instead
of success.
Fixes: 78e6427b4e7b ("coresight: funnel: Support static funnel")
