Hi James,
this patch is just a cross-port of your 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 catched by ahd_find_syncrate() anyway.
Cheers,
Hannes
