From ec693fe5287e1791f4d206e81ebdfdc7d1f8f6b9 Mon Sep 17 00:00:00 2001 From: Jean Delvare Date: Wed, 25 May 2011 20:43:33 +0200 Subject: [PATCH] hwmon: (abituguru) Depend on DMI The abituguru drivers are only built on X86, where DMI support is now enabled by default. So let these drivers depend on DMI, for the following gains: * Robustness and safety. Detection of these devices is weak and uses non-standard methods, it should really be limited to Abit boards unless the user explicitly asks otherwise. * Code simplicity. The code is easier to read without ifdefs. * Better build testing coverage. Now there's only one way to build the drivers, so no risk of build failure on exotic systems.
