Subject: [PATCH net-next v5 04/13] net: sfp: Add helper to return the SFP bus name
Date: Thu, 21 Dec 2023 19:00:37 +0100 [thread overview]
Message-ID: <20231221180047.1924733-5-maxime.chevallier@bootlin.com> (raw)
In-Reply-To: <20231221180047.1924733-1-maxime.chevallier@bootlin.com>
Knowing the bus name is helpful when we want to expose the link topology
to userspace, add a helper to return the SFP bus name.
Signed-off-by: Maxime Chevallier <maxime.chevallier@bootlin.com>
