From 218ee5f364ed006403f1bbe3c1da5af51b1bdb2a Mon Sep 17 00:00:00 2001 From: Bartlomiej Zolnierkiewicz Date: Sat, 13 Oct 2007 17:47:49 +0200 Subject: [PATCH] ide-pmac: remove extra good status wait from pmac_ide_do_setfeature() Don't check for good device status before executing the command in pmac_ide_do_setfeature() (ide_config_drive_speed() doesn't do this). It is a job of upper layers to guarantee that the device is ready to accept new command before we get here.
