That certainly used to be the case...
At the beginning I think as the same as you, and also add the code to get the data as I do in <drivers/misc/atmel-ssc.c>. However, as I remember, I2C seems only use the compatible string after the comma, that means only for "wlf,wm8904", it uses "wm8904" to match. So, I remove all the code I added, and just keep these, and it can get the device type correctly.
So, when I submit the patch and keep the code as simple as possible. Thanks. Best Regards, Bo Shen -- To unsubscribe from this list: send the line "unsubscribe devicetree" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
