Subject: [PATCH v2 5/7] usb: typec: tps6598x: Start using struct typec_operations
Date: Fri,  4 Oct 2019 18:08:15 +0300
Message-ID: <20191004150817.45413-6-heikki.krogerus@linux.intel.com> (raw)
In-Reply-To: <20191004150817.45413-1-heikki.krogerus@linux.intel.com>

Supplying the operation callbacks as part of a struct
typec_operations instead of as part of struct
typec_capability during port registration. After this there
is not need to keep the capabilities stored anywhere in the
driver.
