Not so much; at least for audio it's being handled with platform
specific bodges as far as I've seen so far.  If there had been a
standard way of doing this I'd have expected to see it in this patch
series.  The Google systems all use Qualcomm chipsets which aren't
affected by this since the audio CODEC is hidden from Linux and none of
the audio actually uses ALSA at all in the BSPs I looked at.

It's entirely possible I'm missing something here, everything I know has
come from either talking to users or trawling code on the internet.
