From 04d09b0e62f2180a7e3fa8578ed778eca0c454fd Mon Sep 17 00:00:00 2001 From: Bartlomiej Zolnierkiewicz Date: Fri, 27 Mar 2009 12:46:38 +0100 Subject: [PATCH] ide: set IDE_TFLAG_WRITE basing on data phase used in ide_taskfile_ioctl() Also take care of fixing up incorrect TASKFILE_IN_DMA[Q] data phase when IDE_DRIVE_TASK_RAW_WRITE is requested (no need to do it for TASKFILE_NO_DATA and TASKFILE_[MULTI]_IN -- it had no chance of working previously).
