From 5bfb151f1f565e6082304a30e8c81dfb6ed0b0c8 Mon Sep 17 00:00:00 2001 From: Joao Ramos Date: Mon, 15 Jun 2009 22:13:44 +0200 Subject: ide: do not access ide_drive_t 'drive_data' field directly Change ide_drive_t 'drive_data' field from 'unsigned int' type to 'void *' type, allowing a wider range of values/types to be stored in this field. Added 'ide_get_drivedata' and 'ide_set_drivedata' helpers to get and set the 'drive_data' field. Fixed all host drivers to maintain coherency with the change in the 'drive_data' field type.
