Subject: [PATCH 19/38] cxlflash: Support AFU state toggling
Date: Thu, 22 Feb 2018 16:25:32 -0600 [thread overview]
Message-ID: <1519338332-52470-1-git-send-email-ukrishn@linux.vnet.ibm.com> (raw)
In-Reply-To: <1519338010-51782-1-git-send-email-ukrishn@linux.vnet.ibm.com>
The AFU should be enabled following a successful configuration and
disabled near the end of the cleanup path.
