Subject: [PATCH 8/9] tee: optee: Drop ffa_ops in optee_ffa structure
Date:   Tue, 30 Aug 2022 11:06:59 +0100
Message-Id: <20220830100700.344594-9-sudeep.holla@arm.com>

Since the ffa_device itself carries ffa_dev_ops now, there is no need
to keep a copy in optee_ffa structure.

Drop ffa_ops in the optee_ffa structure as it is not needed anymore.
