From 9a3c49be5c5f7388eefb712be9a383904140532e Mon Sep 17 00:00:00 2001 From: Bartlomiej Zolnierkiewicz Date: Fri, 25 Jan 2008 22:17:07 +0100 Subject: ide: add ide_no_data_taskfile() helper * Add ide_no_data_taskfile() helper and convert ide_raw_taskfile() w/ NO DATA protocol users to use it instead. * Set ->data_phase explicitly in ide_no_data_taskfile() (TASKFILE_NO_DATA is defined as 0x0000). * Unexport task_no_data_intr().
