From d2d4e780aff2fab46a792ebc89f80d1a6872b325 Mon Sep 17 00:00:00 2001 From: Bartlomiej Zolnierkiewicz Date: Mon, 18 Jan 2010 07:20:28 +0000 Subject: ide: add drive->pio_mode field Add pio_mode field to ide_drive_t matching pio_mode field used in struct ata_device. The validity of the field is restricted to ->set_pio_mode method only currently in IDE subsystem. Signed-off-by: Bartlomiej Zolnierkiewicz Signed-off-by: David S.
