Hi Geert
grep asahi-kasei sound/soc/codecs/* sound/soc/codecs/ak4104.c: { .compatible = "asahi-kasei,ak4104", }, sound/soc/codecs/ak4554.c: { .compatible = "asahi-kasei,ak4554" }, sound/soc/codecs/ak4642.c: { .compatible = "asahi-kasei,ak4642", .data = &ak4642_drvdata}, sound/soc/codecs/ak4642.c: { .compatible = "asahi-kasei,ak4643", .data = &ak4643_drvdata}, sound/soc/codecs/ak4642.c: { .compatible = "asahi-kasei,ak4648", .data = &ak4648_drvdata}, sound/soc/codecs/ak5386.c: { .compatible = "asahi-kasei,ak5386", },
ak4642 driver can't probe by "ak";
That's bad. And all but one of these match entries have been added _after_ the addition of "ak" to vendor-prefixes.txt...
Outside sound, there's also "asahi-kasei,ak8975" vs. "ak,ak8975".
In my quick check, The driver which is supporting "ak" is only ak8975. Other Asahi-Kasei driver is using "asahi-kasei".
Very interesting is that the document of ak8975 ./Documentation/devicetree/bindings/iio/magnetometer/ak8975.txt said it should be "asahi-kasei"
what is the policy of Documentation/devicetree/bindings/vendor-prefixes.txt ?
