The patch titled
pata_via: use cable_detect method
has been removed from the -mm tree. Its filename was
pata_via-use-cable_detect-method.patch
This patch was dropped because an updated version will be merged
------------------------------------------------------
Subject: pata_via: use cable_detect method
From: Alan Cox <alan@xxxxxxxxxxxxxxxxxxx>
We end up shifting a few bits of logic around in this driver but the basic
change is the same.
