Do you get proper values when you use the old madc > API with the patchset applied? It works without converting to iio consumer (at least I get some reasonable values). With conversion it fails with above error. I recheck (add printk to iio twl4030-madc) that madc driver is loaded. Could this be that twl4030_madc_battery is loaded earlier then twl4030_madc and than it fails to get iio channels? > > -- Sebastian BR, marek -- as simple and primitive as possible ------------------------------------------------- Marek Belisko - OPEN-NANDRA Freelance Developer Ruska Nova Ves 219 | Presov, 08005 Slovak Republic Tel: +421 915 052 184 skype: marekwhite twitter: #opennandra web: http://open-nandra.com -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
