Subject: [PATCH V5 03/31] smartpqi: add support for product id
Date: Thu, 11 Mar 2021 14:15:09 -0600 [thread overview]
Message-ID: <161549370966.25025.2968242206975557607.stgit@brunhilda> (raw)
In-Reply-To: <161549045434.25025.17473629602756431540.stgit@brunhilda>
From: Kevin Barnett <kevin.barnett@microchip.com>
Add in support for newer HW by adding in a
product identifier. This identifier can then be used
to check for the hardware generation.
