Subject: [net PATCH 3/9] octeontx2-af: Do not allocate memory for devlink private
Date: Tue, 16 Mar 2021 14:57:07 +0530 [thread overview]
Message-ID: <1615886833-71688-4-git-send-email-hkelam@marvell.com> (raw)
In-Reply-To: <1615886833-71688-1-git-send-email-hkelam@marvell.com>
From: Subbaraya Sundeep <sbhatta@marvell.com>
Memory for driver private structure rvu_devlink is
also allocated during devlink_alloc. Hence use
the allocated memory by devlink_alloc and access it
by devlink_priv call.
Fixes: fae06da4("octeontx2-af: Add devlink suppoort to af driver")
