From fecf97882a8f1e9b52627c30322232c18060aa2c Mon Sep 17 00:00:00 2001 From: Andrew Vasquez Date: Mon, 12 Mar 2007 10:41:29 -0700 Subject: [SCSI] qla2xxx: Drop acquisition of hardware_lock during flash manipulations. There's no need given, I/O has been quiesced, RISC interrupts have been disabled, and finally the RISC has been paused. Flash manipulation on ISP21xx, ISP22xx, and ISP23xx parts requires the RISC to go through a full reset to recover.
