There is no non-regmap I/O support in soc-io, anything using the soc-io hw_read() function must be using regmap.case SND_SOC_REGMAP: /* Device has made its own regmap arrangements */ - codec->using_regmap = true;Again, this makes no sense. If we're explicitly being asked to use regmap then we should be using regmap or just failing to set up I/O (which is obviously a catastrophic failure).
How much work is there involved in regmap:ing a device, so that dev_get_regmap() doesn't fail?
