Subject: [PATCH 3/4] staging: dpaa2-ethsw: move port switchdev blocking notifier per ethsw
Date: Mon, 11 Nov 2019 18:50:57 +0200 [thread overview]
Message-ID: <1573491058-24766-4-git-send-email-ioana.ciornei@nxp.com> (raw)
In-Reply-To: <1573491058-24766-1-git-send-email-ioana.ciornei@nxp.com>
Register a different switchdev blocking notifier block per ethsw
instance. When probing multiple dpaa2-ethsw instances, without this the
register will fail.
