Thanks for the reviews.

So when you get -EPROBE_DEFER, you omit the error message _and_
ignore
the -EPROBE_DEFER. Is that really what you want to do?
Oh, you're right. I should return the -EPROBE_DEFER.

I just want to ignore the error msg because gce clk may not ready while
gce probing.

I'll update this patch at next version.
