On failure, the platform_get_irq_byname prints an error message
so, patch removes error message related to this function from
core.c file.
A change was suggested during reviewing CDNSP driver by Chunfeng Yun.

It's the same - cdns->dev_irq == -EPROBE_DEFER < 0

It should be:
if (cdns->dev_irq < 0 || cdns->dev_irq == -EPROBE_DEFER)
or event
if (cdns->dev_irq < 0)
Am I right ?

Yeah, at both places just
if (cdns->dev_irq < 0)
return cdns->dev_irq;
should be enough.
