Subject: [PATCH 04/17] cxlflash: Update sysfs helper routines to pass config structure
Date: Wed, 12 Apr 2017 14:13:34 -0500 [thread overview]
Message-ID: <1492024414-55770-1-git-send-email-ukrishn@linux.vnet.ibm.com> (raw)
In-Reply-To: <1492024215-55579-1-git-send-email-ukrishn@linux.vnet.ibm.com>
From: "Matthew R. Ochs" <mrochs@linux.vnet.ibm.com>
As staging for future function, pass the config pointer instead of the
AFU pointer for port-related sysfs helper routines.
