From a5326f86ebbb153f62b0027a0f367a41f7edc1f6 Mon Sep 17 00:00:00 2001 From: Giridhar Malavali Date: Tue, 24 Mar 2009 09:07:56 -0700 Subject: [PATCH] [SCSI] qla2xxx: Consolidate queuecommand implementations. Post refactoring/multi-queue additions essentially eliminated the need for separate ISP24XX+ queuecommand as isp_ops contains a function pointer to the associated 'start_scsi()' operation.
