Subject: [PATCH v3 2/6] usb: typec: Declare the typec_class static
Date: Wed, 31 Mar 2021 13:59:04 +0300 [thread overview]
Message-ID: <20210331105908.67066-3-heikki.krogerus@linux.intel.com> (raw)
In-Reply-To: <20210331105908.67066-1-heikki.krogerus@linux.intel.com>
This is only to make the handling of the class consistent
with the two other susbsystems - the alt mode bus and the
mux class.
