From c9ff9e7b64138d87023b733e618f29a1d58543f7 Mon Sep 17 00:00:00 2001 From: Sergei Shtylyov Date: Wed, 8 Apr 2009 14:13:03 +0200 Subject: ide: refactor tf_load() method Simplify tf_load() method, making it deal only with 'struct ide_taskfile' and the validity flags that the upper layer passes, and moving the code that deals with the high order bytes into the only function interested, do_rw_taskfile(). This should stop the needless code duplication in this method and so make it about twice smaller than it was; along with simplifying the setup for the method call, this should save both time and space...
