From d2afb3ae04e36dbc6e9eb2d8bd54406ff7b6b3bd Mon Sep 17 00:00:00 2001 From: Daniel Walker Date: Mon, 14 Aug 2006 23:09:23 -0700 Subject: [SCSI] BusLogic gcc 4.1 warning fixes - Reworked all the very long lines in that block (this drivers full of them though) - Returns an error in three places that it didn't before. - Properly clean up after a scsi_add_host() failure.
