From c7f476023f57145357df32346b7de9202ce47d5f Mon Sep 17 00:00:00 2001 From: Mark Haverkamp Date: Wed, 3 Aug 2005 15:38:55 -0700 Subject: [SCSI] aacraid: driver version update Received from Mark Salyzyn from Adaptec. Fixes a bug in check_revision. It should return the driver version not the firmware version. Update driver version number. Update driver version string.

Shutdown should also disable the adapter's interrupt when shutdown (in particularly if the driver is rmmod'd) to prevent spurious hardware activities.
