From dceab655d9f7d99881c2033c8ff4e1c7b444e104 Mon Sep 17 00:00:00 2001 From: Christof Schmitt Date: Fri, 15 May 2009 13:18:18 +0200 Subject: [PATCH] [SCSI] zfcp: Add comments to switch/case fallthroughs Add comments where there is a deliberate fall through in switch/case statements. This makes some code checkers happy and makes it clear that there is no missing break statement.
