Revision 378008dfc72baed2d9c0f0a40dababc0e8901207 authored by Hans de Goede on 14 July 2014, 07:14:34 UTC, committed by Matthew Garrett on 16 August 2014, 08:23:55 UTC
The actual x401u does not use the so named x401u quirk but the x55u quirk. All that the x401u quirk does it setting wapf to 4, so rename it to wapf4 to stop the confusion. Signed-off-by: Hans de Goede <hdegoede@redhat.com> Signed-off-by: Matthew Garrett <matthew.garrett@nebula.com>
