Maybe this printk is redundant but it's more comfortable in use.
To debug I can simply enable cdns-dev events (echo cdnsp-dev:* > set_event)
and I will get the full picture of what the driver is doing.

Otherwise, I must remember which function I need to add to set_ftrace_filter.
Of course, by default I can simply add all cdnsp* functions (echo cdnsp* > set_ftrace_filter) but it
increases the trace log and makes it a little more difficult to analyze.

So maybe in some cases we shouldn't complain for such printk ?

It's my private opinion and not necessarily correct :)

Thanks,
Pawel Laszczak
