Subject: [PATCH 5/7] usb: typec: tps6598x: Start using struct typec_operations
Date: Tue, 1 Oct 2019 12:48:56 +0300
Message-ID: <20191001094858.68643-6-heikki.krogerus@linux.intel.com> (raw)
In-Reply-To: <20191001094858.68643-1-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.
