From ed0de87ce6be92bd84858ad496ffaf60344495a3 Mon Sep 17 00:00:00 2001 From: Giridhar Malavali Date: Wed, 30 Mar 2011 11:46:29 -0700 Subject: [PATCH] [SCSI] qla2xxx: Add the ql2xdontresethba module_param. Also, change the ISP82xx code to only reset if this module_param is set and reset is intended via the QLA82XX_DEV_NEED_RESET case.
