They are two unrelated changes that I should have separated.

The current code is using success_expected to _not_ log an error if
that initial request fails. i.e we silently return -EIO here.

I think the 'success_expected' parameter is not really necessary.
We can simply log the message even for that initial request.

And we can log it a lower priority than KERN_ERR since the message
is mostly for developers rather than users who would use event names
(which encode/abstract the domain and offset values).
