While I haven't tested it (nor can I) so don't take my word for it, it
looks to me as if regular DTS hogs *should* work. If anything, the way
this quirk is implemented in your patch moves the export past the chip
registration, while ordinary hogs would be applied when the chip is
first added.

Am I missing something?
