From 745483f10c6cefb303007c6873e2bfce54efa8ed Mon Sep 17 00:00:00 2001 From: Sergei Shtylyov Date: Wed, 8 Apr 2009 14:13:02 +0200 Subject: ide: simplify 'struct ide_taskfile' Make 'struct ide_taskfile' cover only 8 register values and thus put two such fields ('tf' and 'hob') into 'struct ide_cmd', dropping unnecessary 'tf_array' field from it. This required changing the prototype of ide_get_lba_addr() and ide_tf_dump().
