[SCSI] aic79xx: Remove busyq
From: Jeff Garzik <jgarzik@pobox.com> This patch removes the busyq in aic79xx and uses the command-queue from the midlayer instead. Additionally some dead code is removed. Signed-off-by: Hannes Reinecke <hare@suse.de> Fixed rejections Signed-off-by: James Bottomley <James.Bottomley@SteelEye.com>
