Hmm, it all looks plausible, and I'm again left wondering how the code
passed testing over the last year (I've been running this code for
ages both on iMX6 and Dove, where deferred probing does happen.)

Your patch looks like the right thing to do, so I'll add it to the
component tree shortly - it should end up in linux-next in a few days
time.

Thanks.
