Subject: [RFC PATCH 1/2] platform/x86: uniwill-laptop: Introduce device descriptor system
From: Armin Wolf <W_Armin@....de>
Future additions to the driver will depend on device-specific
initialization steps. Extend the DMI-based feature detection system
to include device descriptors. Each descriptor contains a bitmap of
supported features and a set of callback for performing
device-specific initialization.
