commit a9dd41a1c5f3f00ef790fb071c135900598acab5
Author: Stefan Reinauer <reinauer at chromium.org>
Date:   Fri Oct 14 12:41:46 2011 -0700

    sconfig: check whether component directory actually exists
    
    and add drivers/generic/generic back (empty), since it is used by many
    devicetree.cb files.
    
    Without this patch typos in component names in devicetree.cb cause
    the component to be silently ignored.
