From a7a6f65a39a75a5821eb9aad157326c30f8bbb07 Mon Sep 17 00:00:00 2001 From: Mateusz Jończyk Date: Sat, 12 Feb 2022 13:56:53 +0100 Subject: x86/Kconfig: move and modify CONFIG_I8K MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit In Kconfig, inside the "Processor type and features" menu, there is the CONFIG_I8K option: "Dell i8k legacy laptop support". This is very confusing - enabling CONFIG_I8K is not required for the kernel to support old Dell laptops. This option is specific to the dell-smm-hwmon driver, which mostly exports some hardware monitoring information and allows the user to change fan speed. This option is misplaced, so move CONFIG_I8K to drivers/hwmon/Kconfig, where it belongs. Also, modify the dependency order - change select SENSORS_DELL_SMM to depends on SENSORS_DELL_SMM as it is just a configuration option of dell-smm-hwmon. This includes changing the option type from tristate to bool. It was tristate because it could select CONFIG_SENSORS_DELL_SMM=m . When running "make oldconfig" on configurations with CONFIG_SENSORS_DELL_SMM enabled , this change will result in an additional question (which could be printed several times during bisecting). I think that tidying up the configuration is worth it, though. Next patch tweaks the description of CONFIG_I8K.
