Subject: [PATCH 05/14] usb: typec: tps6598x: Start using struct typec_operations
Date: Thu, 26 Sep 2019 13:07:23 +0300	[thread overview]
Message-ID: <20190926100727.71117-6-heikki.krogerus@linux.intel.com> (raw)
In-Reply-To: <20190926100727.71117-1-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.
