Subject: [PATCH v4 7/9] usb: typec: hd3ss3220: Start using struct typec_operations
Date: Fri, 11 Oct 2019 18:32:17 +0300
Message-ID: <20191011153219.35701-8-heikki.krogerus@linux.intel.com> (raw)
In-Reply-To: <20191011153219.35701-1-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.
