Subject: [PATCH 2/3] IB/core cleanup: Add const on args - device->process_mad
From: ira.weiny () intel ! com
Date: 2015-05-31 21:15:30
Message-ID: 1433106931-5215-3-git-send-email-ira.weiny () intel ! com
[Download RAW message or body]
From: Ira Weiny <ira.weiny@intel.com>
The process_mad device function declares some parameters as "in". Make those
parameters const and adjust the call tree under process_mad in the various
drivers accordingly.
