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.
