From d1c61909c05ead100f855e640fba53925d0665ac Mon Sep 17 00:00:00 2001 From: Andrew Vasquez Date: Wed, 17 May 2006 15:09:00 -0700 Subject: [PATCH] [SCSI] qla2xxx: Update ISP24xx firwmare loading heuristics. If firmware image is unavailable via request_firwmare(), then attempt to load the image (likely out-of-date) stored in flash memory.
