method is really dangerous. I think the real takeaway here is to replace
the linked lists with a different data structure without this unsafe
footgun, but for now we fix the bugs and add a warning to the docs.

The reference taken to the sync provider OF node when probing the
platform device is currently only dropped if the set_sync() callback
fails during DAI probe.
Make sure to drop the reference on platform probe failures (e.g. probe
deferral) and on driver unbind.
This also avoids a potential use-after-... | ```diff
