Subject: [PATCH v1 2/2] net: dsa: rtl8366rb: Quick fix to work with fw_devlink=on
Date: Thu, 26 Aug 2021 00:45:25 -0700 [thread overview]
Message-ID: <20210826074526.825517-3-saravanak@google.com> (raw)
In-Reply-To: <20210826074526.825517-1-saravanak@google.com>
This is just a quick fix to make this driver work with fw_devlink=on.
The proper fix might need a significant amount of rework of the driver
of the framework to use a component device model.
