From 22aa4b32a19b1f231d4ce7e9af6354b577a22a35 Mon Sep 17 00:00:00 2001 From: Bartlomiej Zolnierkiewicz Date: Fri, 27 Mar 2009 12:46:37 +0100 Subject: [PATCH] ide: remove ide_task_t typedef While at it: - rename struct ide_task_s to struct ide_cmd - remove stale comments from idedisk_{read_native,set}_max_address() - drop unused 'cmd' argument from ide_{cmd,task}_ioctl() - drop unused 'task' argument from tx4939ide_tf_load_fixup() - rename ide_complete_task() to ide_complete_cmd() - use consistent naming for struct ide_cmd variables There should be no functional changes caused by this patch.
