From bac08cee93f9cb37b40ecfa8eaf1f6d8daf3909b Mon Sep 17 00:00:00 2001 From: Sergei Shtylyov Date: Tue, 31 Mar 2009 20:15:31 +0200 Subject: [PATCH] ide: call {in|out}put_data() methods from tf_{read|load}() methods (take 2) Handle IDE_FTFLAG_{IN|OUT}_DATA flags in tf_{read|load}() methods by calling {in|out}put_data() methods to transfer 2 bytes -- this will allow us to move that handling out of those methods altogether...
