From c961922b73dab429a759f560952fd4c3f60bd6b3 Mon Sep 17 00:00:00 2001 From: Alan Cox Date: Tue, 26 Sep 2006 17:53:38 +0100 Subject: [PATCH] libata-eh: Remove layering violation and duplication when handling absent ports This removes the layering violation where drivers have to fiddle directly with EH flags. Instead we now recognize -ENOENT means "no port" and do the handling in the core code. This also removes an instance of a call to disable the port, and an identical printk from each driver doing this. Even better - future rule changes will be in one place only.
