From d4e3e04d789ba23027c66e176b10ac7477906948 Mon Sep 17 00:00:00 2001 From: Andrew Vasquez Date: Wed, 17 May 2006 15:09:50 -0700 Subject: [SCSI] qla2xxx: Consolidate firmware-dump handling across ISPs. Simplify and centralise buffer allocation/deallocation, as there's no point in having two memory request methods.
