Lennart, Your s270 platform driver needs a different home in the source tree outside of drivers/acpi/, and the patch that adds it must add an entry to MAINTAINERS. lcd brightness platform support should talk to the existing backlight stuff under sysfs. wlan and bluetooth indicators/controls need to appear under generic places under sysfs -- not under platform specific files under /proc/acpi. Yes, the existing platform specific drivers such as asus, toshiba, and ibm are bad examples. thanks, -Len - To unsubscribe from this list: send the line "unsubscribe linux-acpi" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
