[PATCH 10/18] ide: change order of register access in ide_config_drive_speed()

From: Bartlomiej Zolnierkiewicz
Date: Fri Jun 20 2008 - 17:35:24 EST


Write ATA Feature register before ATA Sector Count register as
a preparation to use ->tf_load in ide_config_drive_speed().

This change shouldn't affect anything (just an usual paranoia).
