Hi Alex

It is impossible to see just looking what the NULL means. And given
its the first parameter, it should be quite important. I find this API
pretty bad.

I actually don't like the first argument. I would have
supplied the main IPA pointer, but that isn't always
visible or available (the GSI code doesn't have the
IPA pointer definition). So I thought instead I could
at least supply the underlying device if available,
and use dev_err().

But I wouldn't mind just getting rid of the first
argument and having a failed assertion always call
pr_err() and not dev_err().

The thing of most value to me the asserted condition.
