From a6b2c5d4754dc539a560fdf0d3fb78a14174394a Mon Sep 17 00:00:00 2001 From: Alan Cox Date: Mon, 22 May 2006 16:59:59 +0100 Subject: [PATCH] PATCH: libata. Add ->data_xfer method We need to pass the device in order to do per device checks such as 32bit I/O enables. With the changes to include dev->ap we now don't have to add parameters however just clean them up. Also add data_xfer methods to the existing drivers except ata_piix (which is in the other block of patches). If you reject the piix one just add a data_xfer to it...
