From 52b5cfb355b2b3274979d25490f190d478ab1fad Mon Sep 17 00:00:00 2001 From: Hannes Reinecke Date: Thu, 4 Aug 2005 09:16:59 +0200 Subject: [SCSI] aic79xx: fixup DT setting this patch is just a cross-port of the fixup for aic7xxx DT settings. As the same restrictions apply for aic79xx also (DT requires wide transfers) the dt setting routine should be modified equivalently. And an invalid period setting will be caught by ahd_find_syncrate() anyway.
