[v2 PATCH 11/36] crypto: virtio - Remove prepare/unprepare request

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



The callbacks for prepare and unprepare request in crypto_engine
is superfluous.  They can be done directly from do_one_request.

Move the code into do_one_request and remove the unused callbacks.
