Probably, yeah - there were other problems with that driver that make me
question if it ever worked properly IIRC. There is a default call to
set cache I/O already but it relies on dev_get_regmap().

That's not for this and is likely to create confusion - that's for
handling early init with syscon type devices, allowing the regmap to be
created with no device and then have the device attached later. I'd
need to look through and see what happens if two devices share a regmap,
perhaps it'd actually be OK, but we can always just allow the regmap to
be overridden at the ASoC level.
